[SOLVED] how to do a THD analysis for a diffirential amplifier

Blackuni said:

Hi,

I presume that u wnt 2 simulate THD!! If so,
Either u can try using distrortion analysis function in SPICE tools, In hspice its ".disto" , this will give better results only if there are no time varying signals. if you hve time varying signals thn do a transient simulation with appropriate inputs and take FFT.
