The circuit shown above is a precision half wave rectifier.
a) Choose standard values for R1, R2, and R3 that will produce the desired waveforms of this circuit.
b) Sketch the voltages vi, vx and vo using a sinewave of vi with an amplitude of 5 volts. Consider diodes D1 and D2 to be non-ideal with a turn on voltage of 750 millivolts.
c) Perform a PSPICE simulation of voltages vi, vx and vo.
