Question

may be use proposed circuit. what value should R have? solve (i) and(iii). alpha,beta,gamma,epsilon=1

1. Design a circuit whose input-output characteristic is as shown in Figure 1. Slope=m Slope=k Slope=m Figure 1 Draw schematic and show the analysis that proves your design will operate as desired. You can assume that all diodes you use are ideal with a threshold of 0.7V. Take Ve- (5000+a) mV, m = (100+ B)/1000 and k = 1. (4 points) Verify your design in LTspice by show simulated V-V. characteristics. (4 points) Add load resistance (R) across output terminal to have k=(50+y)/100 and verify your analysis with LTspice by showing simulated V-V. characteristics Explain how this effect the slope min (0) (2 points)

Answer 1
