In discrete electronics, a common arrangement for implementing a differential amplifier is the long-tailed pair, which is also usually found as the differential element in most op-amp integrated circuits.

A long-tailed pair can be used as an analog multiplier with the differential voltage as one input and the biasing current as another.

Each signal produced by the ECL circuitry was a differential pair, so the signals were balanced.

The Telegrapher's Equations ( or just Telegraph Equations ) are a pair of linear differential equations which describe the voltage and current on an electrical transmission line with distance and time.

Most Category 5 cables are unshielded, relying on the twisted pair design and differential signaling for noise rejection.

In the mathematical field of differential geometry, a metric tensor is a type of function defined on a manifold ( such as a surface in space ) which takes as input a pair of tangent vectors v and w and produces a real number ( scalar ) g ( v, w ) in a way that generalizes many of the familiar properties of the dot product of vectors in Euclidean space.

In mid-twentieth-century systems, the light was reflected to a pair of differential electronic photosensors called a photomultiplier.

The two bases ( or grids or gates ) are inputs which are differentially amplified ( subtracted and multiplied ) by the pair ; they can be fed with a differential ( balanced ) input signal, or one input could be grounded to form a phase splitter circuit.

In contrast with classic amplifying stages that are biased from the side of the base ( and so they are highly β-dependent ), the differential pair is directly biased from the side of the emitters by sinking / injecting the total quiescent current.

The differential pair can be used as an amplifier with a single-ended input if one of the inputs is grounded or fixed to a reference voltage ( usually, the other collector is used as a single-ended output ) This arrangement can be thought as of cascaded common-collector and common-base stages or as a buffered common-base stage.

The input impedance of the differential pair highly depends on the input mode.

The output impedance of the differential pair is high ( especially for the improved differential pair from Fig.

An operational amplifier (" op-amp ") is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output.

The op-amp is one type of differential amplifier.

Other types of differential amplifier include the fully differential amplifier ( similar to the op-amp, but with two outputs ), the instrumentation amplifier ( usually built from three op-amps ), the isolation amplifier ( similar to the instrumentation amplifier, but with tolerance to common-mode voltages that would destroy an ordinary op-amp ), and negative feedback amplifier ( usually built from one or more op-amps and a resistive feedback network ).

The magnitude of A < sub > OL </ sub > is not well controlled by the manufacturing process, and so it is impractical to use an operational amplifier as a stand-alone differential amplifier.

For example, in a non-inverting amplifier ( see the figure on the right ) adding a negative feedback via the voltage divider R < sub > f </ sub >, R < sub > g </ sub > and the differential to single ended conversion is completed without gain losses.

The differential input made a whole range of new functionality possible, but it would not be used for a long time due to the rise of the chopper-stabilized amplifier.

Derived crossovers include active crossovers in which one of the crossover responses is derived from the other through the use of a differential amplifier.

Thus, when a differential amplifier is used to extract this difference, its output constitutes the low pass filter section.

ECL uses an overdriven BJT differential amplifier with single-ended input and limited emitter current to avoid the saturated ( fully on ) region of operation and its slow turn-off behavior.

An instrumentation ( or instrumentational ) amplifier is a type of differential amplifier that has been outfitted with input buffers, which eliminate the need for input impedance matching and thus make the amplifier particularly suitable for use in measurement and test equipment.

The instrumentation of a DMA consists of a displacement sensor such as a linear variable differential transformer, which measures a change in voltage as a result of the instrument probe moving through a magnetic core, a temperature control system or furnace, a drive motor ( a linear motor for probe loading which provides load for the applied force ), a drive shaft support and guidance system to act as a guide for the force from the motor to the sample, and sample clamps in order to hold the sample being tested.
