Question 245: Semiconductors and Logic Gates

Question

Both the diodes used in the circuit shown are
assumed to be ideal and have negligible
resistance when these are forward biased. Built
in potential in each diode is 0.7 V. For the input
voltages shown in the figure, the voltage
(in Volts) at point A is __________.

Accepted Answer

V
A
= 12.7 Ã¢ÂÂ 0.7 = 12 Volt
Diode left hand diode is forward biased and right hand diode is reverse
biased.
