Question

4. (20 points) Sketch and clearly label the transfer characteristic of the circuit for -25 V SVI S +25 V. Assume that the diodes can be represented by a piecewise-linear model with VDo 0.65V and n) 20 Ω. Assuming the specified Zenervo tage o V is measured at a currenL of 10 mA and that 20 Ω, represent the Zener by a piecewise-linear model. Find the following: a. Vu (when Vi =-6 V) is: b. Vo (when Vi 20 V) is: c. The limiter thresholds are: Vin R1 Vout 1k0 Vin D3 R2 0Ω 7D2
