Hi All, if I want to play with the PSR of a circuit block(for exmaple, op-amp), an AC signal is injected into VCC, and I want to use an ideal ac gain block to amplifier this AC signal and convert it to a current source. Would anyone teach me what is the easiest way, to implement Vin(ac) to Iout(ac)? Thank you!
 

Hi

Can't you just use a voltage controlled current source? It might do the job for DC+AC. to be checked
 

Hi Chris, I am wondering that is it a second method to fix the dc and just introduce a gain to ac? Thank you!

Hi

sorry i did not understand what you mean by "is it a second method to fix the dc and just introduce a gain to ac?"

The vccs might do the job, but I am not sure it reproduces the ac current as well. In that case you might want to add an extra ac current source.
