Huang Kai couldn't see what these three circuits are used for. The two op amps were combined with resistors, capacitors, and diodes, and they felt dizzy and couldn't help but say, "Is this circuit useful? It looks quite like that."

Zhang Jun also said: "You said 'look' is OK. This structure is so simple, it looks very difficult!"

Liu Chen didn't argue, since Gao Jian would use P-p-private ms, he would soon be able to distinguish them.

Han Jiaren was beside him, quietly giving a thumbs up and laughing, "Brother, you're pretty awesome! I think you can do it."

It's done in less than ten minutes.

Zhang Jun admired: "Dr. Gao, you are so awesome and you can do anything."

Gao Jian ignored him, holding the mouse's hand a little nervous. This guy just mentioned several questions. Could it be that this circuit can really be handled with absolute value? It is indeed much better than op amp plus bridge circuit!

Senior Sister Doudou also came over to watch the fun and said, "How is it, is it OK?"

Gao Jian clicked the mouse very hard, and the simulation operation was carried out without any errors. The circuit was not incorrect. What about the function? Double-clicking the observation point tremblingly, his face changed immediately.

It is clearly shown that the negative half-period of the sine wave is completely turned up, and the absolute value processing is successful!

Huang Kai said in surprise: "My grass, this circuit is really useful."

Gao Jian touched his chin without saying anything, staring at the circuit on the simulation interface tightly, his face feeling a little tight and hot.

The circuits this kid designed casually were actually better than he did! He even drew three more at once! He has always claimed to be a great expert in analog circuit technology and it is difficult for him to accept it.

Immediately simulated the other two pictures, and the results were clearly displayed, which really achieved absolute value processing!

Sister Dou Dou looked at it for a long time and didn't understand at all. She hurriedly said, "What's wrong, what's wrong, what's the point? How can it be used?"

The other three ignored her, and they all knew that it would be useless to explain it to her. This sister has the lowest hardware level, so she may not analyze the operational amplifier circuit. Maybe she doesn’t know what the operational amplifier is!

Gao Jian said angrily with shame: "A simple analog circuit design is nothing great."

Sister Dou Dou stood outside, Yu Guang felt someone coming in, and subconsciously turned to look, almost biting her tongue. "Director Chang...Director Chang."

Huang Kai and Zhang Jun turned their heads to see. Dean Chang was next to him at some point. He was so scared that he was even more afraid than when he saw the director in high school. "Director Chang is better."

"Hello Dean Chang."

Han Jiaren was also very nervous. This is the legendary savage boss, "Hello Dean Chang."

Although Gao Jian is arrogant, he is not stupid. Ao also divides the occasion and the target. He will never speak so aggressively in front of Teacher Lin Yong. In front of Professor Yan, he will certainly maintain respect and politeness. Compared with Chang Qing, he will be too small. It is not an exaggeration to fireflies compare to bright moons and stars.

"Hello, Dean Chang." He also lowered his head slightly and said.

Unexpectedly, I met here, so it was a waste of trouble. His teacher, Old Man Gong, called him Little Mr. Liu Chen, naturally, would not panic under Chang Qing's powerful pressure. He smiled and nodded slightly, as if he had said hello.

Don’t this guy know about Dean Chang? This is too rude.

Everyone thinks so.

Sister Doudou's eyes were rumbling and thought to herself, "What should I say to Dean Chang?" The condom was almost made to leave a impression on me."

Han Jiaren was determined to pull Liu Chen's clothes, but he was afraid that this little move would be criticized in the eyes of President Chang. Alas, the reputation is too high, there are too many legends. He is timid.

Don't know that the sky is high and the earth is thick.

Don't know what's wrong.

Gao Jian looked at Liu Chen at this moment and was disliked in every way.

"Director Chang, welcome to our group to inspect. Teacher Yan was on a business trip this morning. Teacher Lin went out to do business. I am Dou Dou, a Ph.D. in Class 2003. Now the main research direction is the main control system and communication strategies of wind turbines..."

Among the technicians, Sister Doudou's emotional intelligence is definitely high, especially with the technical masters and teachers.

Gao Jian didn't have this enlightenment.

"I'm not here to inspect. I just walk by and hear you arguing, so I'll come and take a look and talk about an analog circuit?" Chang Qing nodded, his eyes lingering on Liu Chen.

"Yes, Dean Chang, Dr. Gao is instructing several junior brothers to handle the circuits with absolute value." Sister Dou Dou replied first, pretending that she understood very well.

"Is that true?" Chang Qing asked Gao Jian.

"Yeah, yes."

"I listened outside for a while, why do I think he is guiding you?" Chang Qing pointed at Liu Chen and said.

Gao Jian's face suddenly looked bad.

"We're just discussing together. Dr. Gao has a good technical level."

Liu Chen talked to Chang Qing in a very equal tone.

Gao Jian was very ashamed when he heard this. His junior brother was really arrogant.

"Yes, it's true that you are not arrogant or impatient. Little guy, let's go." Chang Qing smiled.

"Let's go." Liu Chen also smiled and nodded.

The conversation between the two was very simple, like a maneuver.

Anyway, the four people next to them were in fog.

The two left one after another.

Sister Dou Dou is the emotional intelligence leader of the group. She first reacted and shouted at Han Jiarenqiu: "Oh, what's going on? What's going on? Are Liu Chen very familiar with Dean Chang?"

I was very upset when I spoke, why didn’t I have a good relationship with my junior brother?

Gao Jian felt ashamed and his face froze. Although no one paid attention to him, he felt very embarrassed. Not only was he compared to others, he was completely killed instantly.

"Damn, what is the background of this junior brother? I absolutely know Dean Chang. Have you heard that? Dean Chang said, "As expected..., this means he knew his junior brother before."

"What awesome thing, no wonder I felt different when I saw him." Han Jiaren murmured.

He was despised by his senior brothers and sisters, and the hindshot was really loud.

These people were excitedly chatting about who Liu Chen was, the rich second generation or the official young man, and they were brainstorming for a while.

Gao Jian didn't feel a little disappointed, but felt that his heart was even more silted. He was very eager to be valued by these big guys and attracted everyone's attention. His cold temper was also a protective color, so please attract attention.

In Chang Qing's office.

Liu Chen sat opposite him with a smile, and Chang Qing skillfully made tea. The whole set of tea sets was simple and shining. It was obviously very ordinary, but he felt extraordinary. Liu Chen didn't understand purple clay, and he didn't know that this was a set of works given by a master.

“Try it.”

I picked it up and took a sip. The temperature was just right, so I drank it directly, "It was refreshing and the tea fragrance was overflowing."

"You boy is not polite at all. I asked me to make tea for you, and I drink it so peacefully."

"Old Chang, what you said is wrong. You are the master and I am the guest. Shouldn't you be entertained? Besides, I don't know how to make tea, I think you enjoy it very much, haha."
