A BJT phase splitter A phase splitter is a device that separates a signal into multiple phases (or polarities). The term is most often applied to amplifiers that produce two "balanced" voltage outputs: of equal amplitude but opposite polarity (i.e. 180 degrees phase difference), but sometimes is used to refer to the generation of quadrature signals (i.e. differing by 90 degrees). The term is not used for logic circuits producing complementary outputs, nor applied to differential amplifiers that have balanced inputs and outputs. Methods using a unity gain inverting amplifier to provide an inverted copy of its input signal; a split-load amplifier (also known as a " cathodyne " or " concertina phase splitter", especially in the context of vacuum tube implementations); a transistor implementation is shown in the diagram; a differential pair amplifier can form a phase splitter in two ways: if the shared emitter (or cathode or source, for...

electronic amplifier, a circuit component Differential amplifier symbol The inverting and non-inverting inputs are distinguished by "−" and "+" symbols (respectively) placed in the amplifier triangle. V s+ and V s− are the power supply voltages; they are often omitted from the diagram for simplicity but must be present in the actual circuit. A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. [1] It is an analog circuit with two inputs Vin− {displaystyle scriptstyle V_{text{in}}^{-}} and Vin+{displaystyle scriptstyle V_{text{in}}^{+}} and one output Vout{displaystyle scriptstyle V_{text{out}}} in which the output is ideally proportional to the difference between the two voltages Vout=A(Vin+− Vin− ){displaystyle V_{text{out}}=A(V_{text{in}}^{+}-V_{text{in}}^{-})} where A{displaystyle scriptstyle A} is the gain of the amplifier. ...

This article is about electric signals via wires. For an immunological model that attempts to explain how T cells survive selection during maturation, see Differential Signaling Hypothesis. Elimination of noise by using differential signaling. Differential signaling is a method for electrically transmitting information using two complementary signals. The technique sends the same electrical signal as a differential pair of signals, each in its own conductor. The pair of conductors can be wires (typically twisted together) or traces on a circuit board. The receiving circuit responds to the electrical difference between the two signals, rather than the difference between a single wire and ground. The opposite technique is called single-ended signaling. Differential pairs are usually found on printed circuit boards, in twisted-pair and ribbon cables, and in connectors.

A SET tube audio amplifier. A single-ended triode ( SET ) is a vacuum tube electronic amplifier that uses a single triode to produce an output, in contrast to a push-pull amplifier which uses a pair of devices with antiphase inputs to generate an output with the wanted signals added and the distortion components subtracted. Single-ended amplifiers normally operate in Class A; push-pull amplifiers can also operate in Classes AB or B [ citation needed ] without excessive net distortion, due to cancellation. The term single-ended triode amplifier is mainly used for output stages of audio power amplifiers. The phrase directly heated triode single-ended triode amplifier (abbreviated to DHT SET ) is used when directly heated triodes are used. There are also single-ended tetrode , beam tetrode/beam power tube/kinkless tetrode , and pentode amplifiers with the same functionality and similar circuitry; e.g. this Mullard design.
