“pulls” current from it when necessary. A common example is the complementary-symmetry push-pull output stage widely used to drive loudspeakers (see illustration), where annpntransistor can source (push) current from a positive power supply into the load, or apnptransistor can sink (pull) ...
A push-pull circuit has a 1st transistor which receives the input signal directly at its gate and a 2nd transistor which has its gate connected to the 1st node. The voltage gain of the source follower circuit which receives the input signal is ≤1, so that gain of the gate voltage ...
Class AB push-pull amplifiers using a pair of complementary metal- oxide-semiconductor CMOS field effect transistors in source- follower connections in its driver stage and using a pair of non-linear current amplifiers with complementary conduction characteristics in its push-pull output stage.收藏...
The performance of a 200W push-pull device and a 110W single-ended device, both using state-of-the-art silicon RF-LDMOS die technology, is described. In the 2.1 GHz band with a two-carrier WCDMA signal applied and a supply voltage of 28V, -37 dBc IM3 and 25-26% drain efficiency is...

摘要: An improved, open-loop push-pull driver is described. Closed-loop feedback loop techniques for control of the push-pull driver are described. These techniques are particularly well adapted to control shoot-through current in a push-pull driver circuit....
FIG. 1 is a schematic diagram of a push-pull amplifier in accordance with a preferred embodiment of the present invention; FIG. 2 is a cross-sectional diagram of a body contacted n-channel metal-oxide-semiconductor (NMOS) silicon-on-insulator (SOI) field effect transistor (FET) in accordance...
In the present investigation the conventional Push-pull amplifier is modified by using some resistors, capacitors and diodes to improve the performance of the circuit. Further the circuit is again modified by using Darlington pair instead of a single transistor which leads the circuit towards the ...
Edwin Henry Colpitts of the Western Electric Company was awarded Patent No. 1,128,292, for an “electric wave amplifier” on February 16, 1915, which covered the push-pull circuit by connecting two vacuum tubes like De Forest’s audions like a primitive precursor to the transistor.3,4Over...
