_________________ is a BJT amplifier that produces outputs that are a function of the difference between two input voltages.

_______________ is the process whereby a portion of the output voltage of an amplifier

is returned to the input with a phase angle that opposes (or subtracts from) the input

signal.

________________ mode of operation that results when the input signal is connected to one input with the other input connected to ground.

________________ mode of operation in which two opposite polarity signals are applied to the inputs.

________________ mode of operation in which two in-phase and equal signals are applied at the two input terminals and the resultant output signal at each output terminal is zero.

________________is the voltage gain of an op-amp with external feedback.

________________ refer to the measure of the amplifier’s ability to reject common-mode signals.

________________ is a very high gain differential amplifier with a high input impedance and low output impedance.

________________ operational amplifier configuration with closed loop gain and attenuation that is equal to unity.

An op-amp contains a number of ______________________ stages to achieve a very high voltage gain.
