hii all

I have some problem about this circuit, i can not prove the effective gain

of the opamp is squared . (my derivation is equal finite gain not square)

can anyone tech me how to prove and how to simulat?

thanks

 

Re: switch-capacitor

Do you want to define gain of the opamp with open feedback ?

hi gevy

what i want to say is

if i give the input with dc +/-0.001v and ideal opamp with finite gain "100"

then i will get the output voltage about 2*(100^2)*0.001

because the paper say this circuit has effective square gain

thanks
