1.	In the circuit shown below voltage Vin is -3V and VB is -1V. The resistor R1 and R2 are 1K. Assume both diodes are identical. Forward bias resistance is 10Ω. Cut-in voltage of diode is 0.7V. The voltage Vout is __________(a) -2V(b) -3V(c) -1V(d) -.0.7VI had been asked this question in an international level competition.Question is taken from Piecewise Linear Model of Diode-2 in chapter Diode Circuit of Analog Circuits
Answer» Right answer is (B) -3V Easy explanation: Since both diodes are in reverse bias mode APPLIED voltage Vin will appear on Vout. Diode D1 and D2 disappears and leaves the terminal as OPEN.
