1.	The output voltage V if Vin = 3V, R = 5K, VB = 2V is ___________ (Use constant voltage drop model assumption and take VD = 0.5V)(a) 0V(b) 2V(c) 1.5V(d) 3.5VThis question was addressed to me by my school principal while I was bunking the class.I want to ask this question from Constant Voltage Drop Model-2 in portion Diode Circuit of Analog Circuits
Answer» Correct CHOICE is (d) 3.5V The best explanation: In constant voltage drop model at FORWARD bias diode can be replaced as a cell and in reverse bias diode can be avoided by considering the terminals are open. Since Vin is reverse bias to the diode all voltage will APPEAR ACROSS diode and no CURRENT flows. Thus, voltage across diode is Vin-VB = 1V. Net voltage V=3V.
