The identical MOSFETs
and
in the circuit given below are ideal and biased in the saturation region.
and
have a transconductance
of 5 mS .
The input signals (in Volts) are:
The output signal
(in Volts) is __________.





Explanation:
Given: MOSFETS
and
: Ideal, Saturation region

DC Analysis:



AC Analysis-
DC Voltage Source = Short-Circuited
DC Current Source = Open-Circuited

In MOSFET based differential amplifier with two
input
and
,
If polarity of
is consider such that
, then
is non-inverting terminal and
is inverting terminal.

As the circuit is symmetrical,
And, 
Thus, 
Hence, option (d) is correct.
