In 1978, I was admitted to Harbin Institute of Technology

Chapter 64 Integrated circuit, isn’t it just multiple circuits integrated together, is that difficult?

“No questions about funding?”

Mo Lingyu stared at Xie Wei with wide eyes, muttering to himself.

What to do if there is no funding?
Xie Wei did not dwell on the fact that the Radio Engineering Department did not give him any job. He could understand that his superiors had assigned him research and development tasks and that they were short of manpower.

The seniors of the class of 77 only entered the school in March this year. They only attended school for half a year longer than the class of 78, so their foundation was not much better. They spent the first half of the year catching up on their high school foundation.

Juniors and seniors are all workers, peasants and soldiers. Except for a very few, their basic knowledge is probably not as good as that of the class of 77.

If there were enough staff, the total number of students admitted in these two classes would not be just 1100.

"As long as we can get it, we support it!"

"Including the chip?"

"You have to look for the computer department for the chips. We only have various electronic components here."

Han Yong reminded Xie Wei that this was the radio engineering laboratory.

Xie Wei was overjoyed and was about to speak.

Han Yong added: "The electronic components you requested cannot exceed what the school laboratory can manufacture. Also, the technical support is limited to what is more difficult for you to provide at the school. The relevant information is open to you..."

"clear."

This support is sufficient.

"Funding? Forget it! The school is so poor, you expect them to give you funding to purchase from other places? Impossible."

When Mo Lingyu asked him why he didn't ask for financial support, Xie Wei replied like this.

"Class monitor, have you offended the people in the Radio Engineering Department?"

Mo Lingyu was even more confused after receiving such an answer.

His big eyes flickered as he stared at Xie Wei. "It's fine if the Radio Engineering Department doesn't send anyone out, but the support they provide must be something that the lab can produce. What will we do if there's no one in the lab?"

"That's what they need to consider. Our biggest challenge lies in the early design, not the subsequent sample trial production and debugging."

Xie Wei explained to Mo Lingyu.

Mo Lingyu has no project experience at all.

We are short of people now. If I want to be less tired, I have to teach her more.

"Our radio project is not difficult. We don't need to design it from scratch. We just need to modify it based on the Silicon Two Watts and the Big Bayi and upgrade it directly from transistors to integrated circuits."

Mo Lingyu looked at Xie Wei.

There was confusion in his clear eyes, not at all tainted by the knowledge Xie Wei had said.

"Let's go to the Computer Science Department. We still need computer science students to participate. We have to ask Director Yu for support."

"Chips? What chips do you want? What do you want them for?"

Yu Guofeng narrowed his eyes and looked at Xie Wei, his tone revealing dissatisfaction.

Mo Lingyu, who followed Xie Wei to the Computer Department, had no time to greet Yu Guofeng when he heard that Director Yu's tone was not right.

He even suspected that Xie Wei had offended not only the people in the radio engineering department, but also the computer department.

"Make a radio and use chips to improve signal processing capabilities..."

Xie Wei grinned and stated his needs.

Yu Guofeng curled his lips and said nothing.

Xie Wei still smiled and said, "Leader, I don't need anything too advanced!"

"Do you want the ECL type (emitter coupled logic circuit) from the 109th Factory under the Academy of Sciences? The 1000 million times large-scale computer of the Chinese Academy of Sciences used this type two years ago. It is the most advanced in China."

A playful smile appeared on Yu Guofeng's face.

"Leader, please don't joke..."

Seeing Yu Guofeng's playful eyes, Xie Wei looked at him with a bitter face.

The ECL emitter-coupled logic circuit is a non-saturated form of digital logic and a basic circuit form of bipolar integrated circuits. It eliminates transistor storage time and achieves high-speed operation.

It is the fastest operating form of all digital integrated circuits.

Fast computing speed and strong load capacity.

The disadvantages are very obvious: high power consumption, poor output level stability, and poor anti-interference ability.

No matter how fast it runs, it cannot be used in communication radio stations that need to be used in harsh outdoor environments due to its high power consumption and poor anti-interference ability.

Yu Guofeng doesn’t know this?

know!

What is ECL type emitter coupled logic circuit?

Mo Lingyu's confused eyes became even more confused.

The expression on his face also became distressed: he wanted to work on a radio project with Xie Wei, but he lacked more basic knowledge!

"Humph! You were kidding first. Didn't you count how much energy the calculator project took up in the department? And you still have the mind to do other things!"

Yu Guofeng snorted coldly, directly expressing his dissatisfaction with Xie Wei.

"You can't blame me for this. I didn't want to do it either, but Teacher Liang Hongbin forced it on me. How about you talk to him and let me give up this project?"

Xie Wei directly put the blame on Liang Hongbin.

Now he is certain that Liang Hongbin's loss of the project is definitely related to Li Rui.

Yu Guofeng blamed himself for digging holes everywhere and killing people without burying them?
Let him find Liang Hongbin or Li Rui.

Yu Guofeng squinted his eyes and looked at Xie Wei, analyzing the truthfulness of his words in his mind.

Mo Lingyu on the side didn't even dare to say a word.

He really wanted to remind Xie Wei that wasn't it said that once the project was completed, the basic physics course would be completed.

This should be used as a reason to convince Director Yu.

"Then go find Liang Hongbin! The Computer Department only has the ECL model. This thing is mainly used to form ultra-high-speed integrated circuits. You know that the school wanted to compete for the billion-times project before..."

Yu Guofeng's face was full of pride.

I gave an explanation, but also expressed my attitude: Don't expect me to help you get the chip you want from other places.

"Of course, if you have time to design it, the lab can help you produce it."

Yu Guofeng’s attitude was very clear: Xie Wei had to design it himself.

With a roll of his eyes, Xie Wei didn't even bother to greet Yu Guofeng and turned away.

"Director Yu, goodbye!"

Seeing Xie Wei leave rudely, Mo Lingyu, who was unfamiliar with Yu Guofeng, hurriedly said hello and followed him out.

"Squad leader, what should we do?"

Coming out of Yu Guofeng's office, Mo Lingyu asked Xie Wei worriedly.

She did not accuse Xie Wei of being rude, which might lead to worse relations with the Computer Science Department.

Xie Wei and Yu Guofeng have a good relationship.

I’m just worried that the project won’t have chips and will fail before it even starts.

Mo Lingyu didn't understand chips and integrated circuits, but from their conversation, he knew very well that chips were the most critical thing.

"What can I do? I'll go find Teacher Liang and see if I can contact other companies for supply. I can't just ignore the project he gave me."

Xie Wei said with a wry smile.

He knew very well that he, the shark, was unwilling to chase the catfish, so these teachers began to force him to run.

When I run, the catfish has to swim even harder.

How can I explain this to Mo Lingyu?

Li Rui just criticized himself, saying that he was too cautious and too slick; Han Yong and Yu Guofeng's attitudes suddenly changed. If Xie Wei still didn't understand the reason, all his efforts would have been in vain.

I don’t know if Li Rui wants to achieve political achievements, so he forces himself like this.

Xie Wei secretly criticized Li Rui and turned to Mo Lingyu.

"Let's go back to class and find out what the students' radio skills are like."

Mo Lingyu looked heavy-hearted and was even more worried that the project would fail in the womb.

"But the problem with the chip..."

"If I can't get it, I'll just do it myself! Fortunately, it's not a large-scale integrated circuit, otherwise my head would be bald."

"Ah? You can also design integrated circuits?"

Mo Lingyu's already big eyes almost widened in an instant.

She really wanted to ask Xie Wei what else he couldn't do.

But she didn't dare ask.

The current class monitor is so strong that all the students in the class despair. They know that they can never catch up with him even if they try their best, but no one wants to be eliminated from the experimental class, let alone lose someone in the experimental class.

"Integrated circuits are not very complicated. They are just interconnecting transistors, capacitors, resistors, inductors and other components and wiring in ordinary circuits... You can think of it as a collection of many circuits together, which makes it simple..."

It’s easy!

Mo Lingyu stared at Xie Wei with wide eyes and when he heard "it's easy", he wanted to knock Xie Wei's head open and then put his brain into his own.

Basic circuits are difficult to learn!
"I'm so stupid!"

Once again, Mo Lingyu felt like a fool.

Knowing full well that in the eyes of a genius like Xie Wei, things that were particularly difficult for them were all very simple, she actually forgot her previous oath: always listen and don't ask questions.

Finally, I asked.

This gave Xie Wei another chance to attack him.
