Sheldon, Thanks for your reply. I though I set maxac freq big enough ( = 100M). More information about my setup : input freq = 12.5K, sampling clock = 200KHz, Bandwidth = 100KHz, amplifier's voltage gain = 72dB ( 3 stages in cascade, each = 24dB) . Input capacitor = 64pF, feedback capacitor = 4pF. When using maxsideband = 20, output noise density = 50.7nV2/Hz. msb = 50 , output noise = 87.7nV2/Hz. That's for the case of one single time point. I am thinking about choosing 2 time points to represent the peaks of output voltage, but i don't know how. Horizon, Thanks for your reply. I don't have access to Eldo. best regards, ha
