Hi, For my switched capacitor amplifier design (input at 12.5Khz, clock at 200Khz, gain = 0dB) I noticed that if my output is non-reset(not return to zero type), then PAC simulation show 0dB with notches at 200Khz, 400Khz and so on.. as expected. But if my output is reset(return to zero type), the PAC simulation shows -6dB gain and notches at 400Khz,800Khz ...?? Please explain. Transient simulation in both cases show 0dB gain. Nothing special about my amplifer, just a conventional switched capacitor amplifier with narrow band CDS technique applied. regards, ha
