Determine ONOFF of the diode circuits and find l and V when

Determine ON/OFF of the diode circuits and find l and V, when the diodes are ideal and when the diodes are non-ideal (use CVD model), respectively.

Solution

(a) In this case , diode is ON because forward biased

I = 2.5mA

V = 5V

(b) In this case diode is OFF because reverse biased

V = -10 V

I = 1 mA
