Hi guys,
im designing a diff two stage opamp. (inverting opamp with Closed loop of R2/R1=-10K/1K)
I am not sure if i have to design a s ource follower in the last stage. For some reason my gain drops to zero only in the last stage where CL and output ports are applied. I am not sure why this is happenening. Is it due to the fact that i didn't design a source follower?
