3. Use matlab to plot the output voltage of an inverting
operational amplifier given the following conditions: K = Gain of
the amplifier = 12.5. Vi = input voltage -2.5 < Vi < 2.5 V],
(use 0.25 increments). V+ = positive power supply voltage, V+ = +20
V. V- = negative power supply voltage V- = -20V. Vo = output
voltage Vo = -KVi Recall that if the output voltage Vo is greater
than V+, or less than V-, the...
1.If an inverting voltage amplifier with a large gain were built
to amplify a small sinusoidal
signal and the output waveform was observed to be sinusoidal but
with a much lower
amplitude than predicted by a theoretical analysis assuming an
ideal operational amplifier,
what non ideal property of the operational amplifier would be
likely contributing to this
degradation in performance?

In a differential amplifier, the non-inverting input is 3 cos
(600t + 45◦) mV and the inverting input is 4cos (600t - 45◦) mV.
The output is vo = 3cos (600t + 45◦) + 4.004cos (600t - 45◦) V. The
CMRR is of ____ dB
with a voltage range of 0.874 and -0.855 how can i design a
inverting amplifier using standard resistors to produce a voltage
output range of -10 to 10 volts?
Problem 5. (10 pts) In a differential amplifier, the
non-inverting input is 3 cos (600t
+ 45◦) mV and the inverting input is 4cos (600t - 45◦) mV. The
output is vo = 3cos (600t + 45◦) + 4.004cos (600t - 45◦) V. The
CMRR is dB
Design a three-stage operational amplifier at the transistor
level using BJT technology. Your design should
include a differential input stage with large input resistance,
a gain stage, and an output stage with low
input resistance. Justify your design choices. Use the op-amp
you designed to create an inverting amplifier
using negative feedback with a given gain, A = −Rf/Ri . Provide
a characterization of your op-amp design which
includes input resistance, output resistance, input bias
currents, input offset current, input...
