problem P3.28
Determine the diode current /D and voltage VD for the circuit in Fig. 3.18 on page 157 of the Text, with VDD 1:5 1.0 V and R - 100 a Consider the diode to be much like the one sketched in Fig. 3.20, having a current of 1 mA at a voltage of 0.7 V, exhibiting a voltage change of 0.1 V per decade of current change. Use an iterative solution of the diode logarithmic voltage-current relationship.
