  • RE: OPA2171: Output doesn't match the input in certain working condition

    Hello Yishan, This circuit seem to be very unusual to me. Input signal is 122kHz and gets doubled by full wave rectification. 2nd step is low pass filter at 160MHz, in other words do almost nothing. 3rd step is to buffer 244kHz (with harmonics) with a…
