A silicon diode has Cj0 = 15 fF. It is biased by a 43-kΩ resistor connected between the cathode of the diode and the input signal, as shown in Fig. P1.4. Initially, the input is 3 V, and then at time 0 it changes to 0 V. Estimate the time it takes for the output voltage to change from 3 V to 0.9 V (i.e., the time). Repeat for an input voltage change from 0 V to 3 V and an output voltage change from 0 V to 2.1 V. Compare your answers to those obtained using a SPICE simulation.
