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.
