Hello folks,
I am doing a preliminary switched cap block-level simulation. For this I need to build an ideal integrator. I thought the "opamp" instance from ahdlLib would do the job with a feedback cap. But, it isn't working ! :-/ Infact, i tried to do an inverting amp with that block(V+=Vdd, V-=gnd!, Vref=?), the tran simulation goes fine but opamp just doesn't work as it should!
Anything I'm missing? What should I connect to the Vref pin? Any pointers please? Thanks, Gau
