but each of feedback circuits works properly when they are not connectoed parallel to eachother by mosfets. But the connection of mosfet's are correct? In addition this sytem will generate negative output as well. So current direction will change. Does Mosfet let current flow in both direction...
Hello
I would like to select gain of differential amp's gain by a controller. I used N channel Mosfets and you can see on attached sch. each of them is working individually. But when I connect them together, the output singal becomes sine wawe. Op amp is TL082. Power supply of opamp is +-18V...
Here is the example of rectifier but I can not see half wave sine as output voltage . How should I analyse the circuit? I have tried with AC Simulation , Transient Simulation. Pls help me, since 2 weeks i am trying to find out.
When I open the example of rectifier from ADS2009, I can not get the output voltage as half wave of sine. How could I get this?

I supply sufficient AC voltage but output voltage is again full wave. What should I do?
