Test Bench for OTA's

Hello all,

I have recently implemented an OTA on silicon and I would like to know how to design a test bench to get all the results that I need. A cursory look at the spec sheets for the LT1014 show open loop gain, noise figures and transient analysis for specific loads. How does one replicate this in real life? (Transient analysis is pretty straightforward I think) For example how does one accurately generate open loop gain since an AC source doesn't exist. I know this question seems silly and in all liklihood will garner comments regarding my education. I have searched the internet and I haven't come across a simple testbench to accomodate what I need.

Any help is always appreciated.

Thanks again, Regards, Sanjay

Open loop gain is only a little bit tricky to measure. What you do is input a low impedance calculatable (possibly sub-microvolt) voltage to the input (either one versus ground) and get it to produce a known output (say 1V rms). Then you know the ratio of input voltage to output voltage.
