1 Design an operational amplifier for low voltage sensor application
using a differential amplifier, In practice if the input voltage v; is set
to zero volt then the output voltage v, should also be zero volt, but the
output is driven to some millivolts.
a) Choose an appropriate compensation technique in order to
make the output voltage as zero, so that it can be used for low
voltage sensor application.
b) Justify the reason why op-amp drives some output voltage,
even input v; is set to zero volt.

c) While using in Low voltage sensor application, Suppose Op-
amp nulled at 25°C, if the temperature is raised to 50°C, then
is there any shift in output voltage, if yes justify your answer,
and suggest any technique to avoid the shift.
d) Imagine that if the op-amp has low input impedance and high
output impedance, then whether the op-amp is suitable for
this application, comment.
