Hi all, if we have a current mirror to generate a current source signal or sink signal, with repetitive rate frequency, such as sine wave, are we able to apply some low pass filtering circuit directly to this current, and generate a close to DC level current? Thank you!
 

I think it would be simpler to filter the mirror's common gate voltage.
 
Connect a big fat cap at the gates of the transistors to ground.
