Since the voltage across the diode is , the current through the loop is obtained by using the relation for the current
To begin the iteration, we assume that
Substituting the values in the relation for the current gives,
From the relation for the diode current, ID given by , we get the relation for VD as
Substituting the values ID= 0.3mA, IS=10-12mA in the relation for the voltage gives
Now find the current by substituting the values VD= 0.66V; VDD= 1 and R = 1 in the relation
On substituting the value of ID= 0.34 mA and /, = 10-12mA in the relation for the voltage, , we get the value for voltage, V.
