Definition of "Push-Pull Amplifier" |
An amplifier that uses two transistors (or electron tubes) whose output signals are in phase opposition, with one amplifier working while the other does not. Read more about a Transistor Amplifier Push-Pull Circuit [on the companion site]. Also related; List of Transistor Manufacturers. Transistor Q1 operates while transistor Q2 is off in the circuit to the right. / A push-pull amplifier is a type of electronic circuit that uses a pair of active devices that alternately supply current to, or absorb current from, a connected load. Push–pull outputs are present in TTL and CMOS digital logic circuits and in some types of amplifiers, and are usually realized as a complementary pair of transistors, one dissipating or sinking current from the load to ground or a negative power supply, and the other supplying or sourcing current to the load from a positive power supply. / 1-persistent CSMA is used in CSMA/CD systems including Ethernet. / amplifier using two active devices operating 180° apart. |
