I want to test if an OTA with differential input/output is working properly. What kind of topology should I use to calculate suitable behavior and gain?The only circuit and topologies I know and find around are for single output amps and I don't know if these can be applied similarly and I am a little confused...
 

For defining the output dc voltage of ota, you need cmfb to get it fixed and also in input you need to put an appropriate dc bias voltage.
 
So I need to send the outputs to the CMFB (Like a simple differential pair) and then use the voltage in the outputs of the CMFB to calculate the voltage gain?An example would be helpful actually...Thanks for the reply....
