Response the below problem:
Q: Plot the transfer characteristic of the circuit in Fig. P4.91 by evaluating vI corresponding to vO = 0.5 V, 0.6 V, 0.7 V, 0.8 V, 0 V, -0.5 V, -0.6 V, -0.7 V, and -0.8 V. Use the exponential model for the diodes, and assume that they have 0.7-V drops at 1-mA currents. Characterize the circuit as a hard or soft limiter. What is the value of K? Estimate L+and L-.
