Question 1

Closed-loop
voltage gain

Answer 1

The net voltage gain of an amplifier
when negative feedback is included.

Question 2

Common mode

Answer 2

A condition characterized by the
presence of the same signal on both
op-amp inputs.

Question 3

Common-mode
rejection ratio
(CMRR)

Answer 3

The ratio of open-loop gain to common-mode gain; a measure of an op-amp’s
ability to reject common-mode signals.

Question 4

Differential
amplifier
(diff-amp)

Answer 4

An amplifier that produces an output
voltage proportional to the difference of
the two input voltages.

Question 5

Differential mode

Answer 5

The input condition of an op-amp in which
opposite polarity signals are applied
to the two inputs.

Question 6

Inverting amplifier

Answer 6

An op-amp closed-loop configuration in
which the input signal is applied to the
inverting input
Draw the circuit

Question 7

Negative feedback

Answer 7

The process of returning a portion of the
output signal to the input of an amplifier
such that it is out of phase with the input
signal

Question 8

Slew rate

Answer 8

The rate of change of the output
voltage of an op-amp in response to a
step input.
