Huang Kai couldn't see what these three circuits were for, the two operational amplifiers with resistors, capacitors, and diodes, he was dizzy when he looked at them, and couldn't help but say: "Is this circuit useful? It looks like that." Pen ~ Fun ~ Pavilion www.biquge.info"

Zhang Jun also said: "You also said that 'looking' is okay, this structure is so simple, it looks enough!"

Liu Chen didn't argue either, since Gao Jian would use PSIM, he would soon tell.

Han Jiaren was next to him, quietly gave a thumbs up, and said with a smile: "Dude, it's pretty good! ”

It was done, in less than ten minutes.

Zhang Jun admired: "Dr. Gao, you are too good, you can do anything." ”

Gao Jian ignored him, the hand holding the mouse was a little nervous, this kid just had a few questions to the point, should this circuit really be able to deal with absolute value, it is indeed much better than the operational amplifier plus bridge circuit!

Senior Sister Doudou also came over to see the excitement and said, "What's the matter, okay?"

Gao Jian clicked the mouse very hard, the simulation was running, there was no error information, and there was no error in the circuit, so what about the function?

It clearly shows that the negative half cycle of the sine wave is all flipped up, and the absolute value is successfully processed!

Huang Kai exclaimed: "My grass, this circuit can really be used." ”

Gao Jian touched his chin and didn't speak, staring closely at the circuit on the simulation interface, his face a little tight and hot.

This kid casually designed circuits that were even better than what he did! He even drew three of them at once! It was difficult for him, who had always boasted of being a master of analog circuit technology, to accept it.

Immediately, the other two graphs were also simulated, and the results were clearly displayed, and the absolute value processing was indeed realized!

Sister Doudou didn't understand it at all after watching it for a long time, and said hurriedly: "What's wrong, what's wrong, what does it mean, how can it be used?"

The other three didn't pay attention to her, and they all knew that it was useless to explain to her, this sister's hardware level is the lowest, and I'm afraid that the operational amplifier circuit will not be analyzed. I don't know what an op amp is!

Gao Jian said angrily with some shame: "A simple analog circuit design is not a big deal. ”

Sister Doudou stood on the outside, and when she felt someone coming in, she subconsciously turned her head to look, and almost bit her tongue. "Chang...... Dean Chang. ”

Huang Kai and Zhang Jun turned their heads to look, and at some point Dean Chang was beside them, they were scared, more afraid than seeing the director of discipline in high school, "Dean Chang is good." ”

"Hello Dean Chang. ”

Han Jiaren was also nervous. This is the legendary poisonous tongue boss, "Hello Dean Chang." ”

Although Gao Jian is arrogant, he is not stupid, he is also arrogant and divided into occasions and objects, he will never speak so impulsively in front of Teacher Lin Yong, in front of Professor Yan, of course, he will maintain respect and politeness, compared with Chang Qing, he is too small. Fireflies are no exaggeration to be brighter than the moon and stars.

"Hello Dean Chang. He also bowed his head slightly.

I didn't expect to meet here, but it was a good thing, his teacher Gong Old Man called him a little gentleman, Liu Chen naturally would not panic under Chang Qing's strong coercion, smiled and nodded slightly, which can be regarded as a greeting.

Doesn't this guy know Dean Chang? This is too rude.

Several people thought so.

Sister Doudou's eyes were grunting, and she thought, what to say to Dean Chang, it's almost a set, so that he can leave a little impression on me.

Han Jiaren had the heart to pull Liu Chen's clothes. I'm afraid that this little action will be criticized in the eyes of Dean Chang, hey, the murderous reputation is too strong, and there are too many legends. Timid.

I don't know how thick the sky is.

I don't know what to do.

Gao Jian looked at Liu Chen at this moment, which was unpleasant.

"Dean Chang, welcome to our group to inspect, Mr. Yan is on a business trip this morning, Mr. Lin goes out to do errands, I am 03 Ph.D. Dou Dou, and now the main research direction is the main control system and communication strategy of wind turbines......"

Among the technicians, Sister Doudou's EQ is definitely high. Especially with the technology gods and teachers.

Gao Jian didn't have this awareness.

"I'm not here to inspect, just walk by and hear you arguing, so I came over to take a look, are you talking about an analog circuit?" Chang Qing nodded, his gaze lingering over Liu Chen's body.

"Yes, Dean Chang, Dr. Gao is instructing a few juniors to process circuits in absolute value. Sister Doudou replied first, pretending that she knew very well.

"Is that the case?" Chang Qing asked Gao Jian.

"Well, yes. ”

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

Gao Jian's face was not good-looking all of a sudden.

"It's just a discussion together, and Dr. Gao's technical level is good. ”

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

Gao Jian was very ashamed when he heard this, his junior brother was really generous.

"Yes, sure enough, it's not arrogant or impatient, little one, let's go. Chang Qing said with a smile.

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

The conversation between the two is very simple, as if it were sharp.

Anyway, the four people next to him were in a fog.

The two left one after the other.

Sister Doudou is the person in charge of emotional intelligence in this group, and she was the first to react, and shouted at Han Jiaren: "Ah, what's going on, what's going on, is Liu Chen very familiar with Dean Chang?"

I was very annoyed with the words, why didn't I have a good relationship with my junior brother.

Gao Jian only felt ashamed of himself, his face stiffened, even though no one paid attention to him, he also felt very embarrassed, not only was he compared to others, but he was completely killed in seconds.

"I'm rubbing, what is the background of this junior brother? I don't know Dean Chang, have you heard, Dean Chang said, you really ...... , which shows that he knew about his junior brother before. ”

"It's so awesome, no wonder I think it's different when I see him. Han Jiaren muttered.

was despised by his senior brothers and sisters, cut, this afterthought was really loud.

These people excitedly chattered about who Liu Chen was, whether he was a rich second generation or an official son, and brainstormed for a while.

Gao Jian didn't feel a moment of loss, he only felt that his chest was even more silty, he was very eager to be valued by these bigwigs and get everyone's attention, and his cold and arrogant temper was also a protective color, so attract attention.

Chang Qing's office.

Liu Chen sat opposite with a smile, Chang Qing skillfully made tea, the whole set of tea sets, simple and transparent, obviously very ordinary, but I felt extraordinary, Liu Chen didn't understand Zisha, and he didn't know that this was a set of works given by the master.

"Taste it. ”

I took a sip of it, the temperature was just right, and I drank it directly, "It's refreshing, and the tea is full of fragrance." ”

"You kid is not polite at all, let me make you tea, and drink so peacefully. ”

"Lao Chang, what you said is not right, you are the host and I are the guest, shouldn't you entertain it? Besides, I don't know how to make tea, I think you enjoy it a lot, haha." ”

Chang Qing had no choice but to become an old man, it sounded quite pleasant, and he laughed along, this young man really has a straight face, and he doesn't have to speak so harshly with a straight face. (To be continued.) )
