Unformatted text preview: in Pspice using D1N4002 diodes (replace the transformers with voltage-controlled voltage sources). Measure V o , V r , I D,max and I D,avg when I L = 400 mA. Provide schematics and all necessary plots with measurements. 3. In the circuit below, the opamp is ideal, and i-v characteristics of the diode is given by I D = I S exp ± V D nV T ² , where I S = 14 nA , n = 2 and V T = 25 mV . (a) Find the small-signal transfer function T ( s ) = v o ( s ) /v i ( s ) . (b) Sketch the magnitude Bode plot of T ( jω ) . (c) Find V o ( t ) for v i ( t ) = 0 . 1 sin(2 π 1000 t ) . (d) Verify your results using Pspice. For the diode, use the model D1N4002. Provide schematics and all necessary plots with measurements. 10u C 1 1k R 1 +-V x 2 500 R 2 U 1 D 1 +-v i V o...
