Solution
RL = 10
Known Quantities: vS (t) = 10 cos( t); V = 06 V; rD = 05
; RS = 1
Find: The load voltage, vL Assumptions: Use the piecewise linear diode model (Figure 835) Analysis: We replace the diode in the circuit of Figure 836 with the piecewise linear
model, as shown in Figure 837 Next, we determine the conduction condition for the ideal diode by applying KVL to the circuit of Figure 837: vS = v1 + v2 + vD + 06 + vL vD = vS v1 v2 06 vL We use the above equation as was done in Example 84 that is, to determine the source voltage value for which the diode rst conducts Observe rst that the diode will be off for

negative values of vS With the diode off, that is, an open circuit, the voltages v1 , v2 , and vL are zero and vD = vS 06 Thus, the condition for the ideal diode to conduct (vD > 0) corresponds to: vS 06 V Diode on condition
Once the diode conducts, we replace the ideal diode with a short circuit, and compute the load voltage using the voltage divider rule The resulting load equations are: vL = 0 vL = RL vS V = 817 cos( t) 052 RS + r D + R L vS < 06 V vS 06 V

Figure 838 (a) Source voltage and recti ed load voltage; (b) Voltage transfer characteristic
It is instructive to compute the transfer characteristic of the diode circuit by generating a plot of vL versus vS This is done with reference to the equation for vL given above; the result is plotted in Figure 838(b)
Comments: The methods developed in this example will be very useful in analyzing
some practical diode circuits in the next section
