3.3 A designer has a supply of diodes for which a current of 2 mA flows at 0.7 V. Using a 1-mA

current source, the designer wishes to create a reference voltage of 1.3 V. Note that you may use

parallel of N diodes stack that will do the job as shown. How many diodes are needed? What is the

exact voltage being achieved?
