an amplifier that has two inputs, each of which is sensitive to the opposite polarity of the other, i
a cicuit that amplifies the difference between two inputs
an electronic amplifier that measures the difference in potential between two electrode locations.
A device which compares two input signals and amplifies the difference between them.
An amplifier in which the output is in proportion to the differences between voltages applied to its two inputs.
A type of amplifier consisting of two transistors in which the difference in the transistor's input signals is amplified. Because of their excellent thermal characteristics, differential amplifiers are used in the first stage of some power amplifiers, phono stages, etc.
An amplifier that produces an output proportional to the difference of two inputs.
An amplifier with two inputs, but only one output which compares two independent input signals and amplifies the difference between them.
A differential amplifier is a type of an electronic amplifier that multiplies the difference between two inputs by some constant factor (the differential gain). A differential amplifier is the input stage of operational amplifiers, or op-amps, and emitter coupled logic gates.
