I built this circuit using a TSH 22 opamp ( quite fast 15V / uS ) and BAT 46 Schottky diodes, it worked but there was a bit of an error in that the peak of the rectified waveform was a bit higher than the peak of the input waveform ( 1 KHz sine wave ) anyone know why that might be ?
I have added the 2K35 resistor to equalise the effect of input bias currents ( important in a precision application like this ) it has no effect on the simulation but would in a real circuit.
