Hi Every one!
I have to do an exercise about analyse electronic circuit. The question is "Analyse the operation of this circuit. I can't understand it. Can you help me?

 

You have to express the two output variables (Vout+ and Vout- as a Boolean Function of the two input variables (Vin+ and Vin-).

 

It looks like an op amp. An op amp has a high input resistance and a low output resistance. It can be configured as the many op amp circuits you have seen. That is, it can be used as an adder, a comparator, etc.... everything an op amp does. And this is based on high R input (ideally infinite impedance) and low R output (ideally, zero ohms output). This amplifier design strives toward that ideal, but it is a practical, non ideal circuit in reality. Nevertheless, you would take this whole circuit and put it in a small triangle on paper and call it an op amp. As for the workings of the circuit, look in your textbook. You should find the answers there.

 

ok, thanks. I am going to try to find it now.
