Question

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 v_i, v_x and v_o using a sinewave of v_i 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 v_i, v_x and v_o.
