One of the more interesting applications of a diode, based on the diode equation, is an electronic thermometer. The concept is based on the empirical observation that if the current through a diode is nearly constant, the offset voltage is nearly a linear function of the diode temperature, as shown in Figure P9.15(a).
a. Show that iD in the circuit of Figure P9.15(b) is nearly constant in the face of variations in the diode voltage vD. To do so, compute the percent change in iD for a given percent change in vD. Assume that vD changes by 10 percent from 0.6 V to 0.66 V.
b. On the basis of the graph of Figure P9.15(a), write an equation for vD (T °) of the form vD = ?T ° + ?
