In 4.49 we investigated the operation of the circuit in Fig. P4.49 for small input signals. In this problem we wish to find the voltage transfer characteristic (VTC) versus for for the case I = 1 mA and each of the diodes exhibits a voltage drop of 0.7 V at a current of 1 mA. Toward this end, use the diode exponential characteristic to construct a table that gives the values of: the current in the 10-k resistor, the current in each of the four diodes, the voltage drop across each of the four diodes, and the input voltage , for , +1 V, +2 V, +5 V, +9 V, +9.9 V, +9.99 V, +10.5 V, +11 V, and +12 V. Use these data, with extrapolation to negative values of and , to sketch the required VTC. Also sketch the VTC that results if I is reduced to 0.5 mA.
