input power. A disadvantage of class B or class AB is that it is more difficult to implement the circuit in order to get a linear reproduction of the input waveform. The term push-pull refers to a common type of class B or class AB amplifier circuit in which two transistors are used on alternating half-

A Class AB amplifier can be made from a standard Class B push–pull stage by biasing both switching transistors into slight conduction, even when no input signal is present.

This is what we did in the lab when we added the transistors connected as diodes to the Class B amplifier to change it to a Class AB amplifier. A further improvement can be made to the circuit by converting the transistors connected as diodes to emitter follower stages, providing a high input impedance to the amplifier.

Weimann, H. Scherer, V. A. Krupenin, J. Niemeyer, and A. B. Zorin, J. Vac. I know many Japanese Amps were Class AB from Adverts.. Are most well known pre 1990 Transistor Amps Class AB or Class B.? I am thinking 28 Jul 2016 A class-AB circuit has two transistors conducting a small idle current then they go push-pull when they have an input signal.

When the voltage at the base is greater than 0.6V (or whatever your transistor's V th might be), the transistor starts saturating and looks like a short circuit between collector and emitter. When the voltage at the base is less than 0.6V the transistor is in cutoff mode -- no current flows because it looks like an open circuit between C and E.

Both NPN and PNP-based class AB behaviors are presented since a push-pull configuration is necessary, such as for the class B amplifier, to combine the positive and negative half-waves in order to reproduce the complete signal. We can note that a small portion of the signal is conducted simultaneously by the NPN and the PNP transistors. A transistor power amplifier's job is that of converting a medium-level medium-impedance AC input signal into a high-level low-impedance state suitable for driving a low-impedance external load. This action can be achieved by operating the transistor (s) in either of two basic modes, known as 'class-A' or 'class-B.' WIth 20mA Icollector and 40 volts, the maximum power dissipation of your first transistor (that common emitter) will be 20mA/2 * 40 volts/2 (for passive loads), or 10mA * 20Volt = 0.2 watts.

WIth 20mA Icollector and 40 volts, the maximum power dissipation of your first transistor (that common emitter) will be 20mA/2 * 40 volts/2 (for passive loads), or 10mA * 20Volt = 0.2 watts. So you need a transistor in the voltage amplifier (gain of 9/0.5 = 18x) able to dissipate 0.2 watts. Probabaly don't worry about that yet.
