2011-08-12 · The class B amplifier uses two transistors. One handles the positive side of the waveform and the other handles the negative side of the waveform. Each transistor is in an off state until the waveform crosses over the zero point and then it must turn on.

MOSFET Power Supply w/ Audiophile Grade IRTM Transistors . Hybrid Aluminum Direct Short, Thermal, & Overload Circuits Protect.

The class AB push-pull output circuit is slightly less efficient than class B because it uses a small quiescent current flowing, to bias the transistors just above cut off as shown in Fig. 5.5.1, but the crossover distortion created by the non-linear section of the transistor’s input characteristic curve, near to cut off in class B is overcome. 4 Transistor Class AB amplifier. Description. A very simple and easy to build class AB audio amplifier using four transistors is shown here.

where I Q is typically small. With the advantage, the disadvantage of these two amplifiers is that it is difficult to implement their circuit to get linear regeneration of the input signal. the term used for class B or class AB amplifier circuitry in which 2 transistors are operating for one half of the signal to regenerate input at the output. The circuit involves a combination of Class A and Class B power amplifiers with a biasing stage connected at the base of the complementary transistors.

This circuit is designed to operate Q6 and Q7 in Class A operation, and can be adjusted to operate output transistors Q8 and Q9 in either Class A or Class AB mode. An alternative to FIG. 5 is presented in FIG. 6, where the feedback connections have been made from X to C and from Y to D through the resistors R6 and R7, but otherwise the circuit is identical to the one shown in FIG. Re: Class AB amplifier circuit not working correctly « Reply #6 on: August 11, 2013, 08:49:23 pm » The output cap is not needed ?, yeah now that I think about it that makes sense, I'm still getting used to building circuits with a positive and negative rail Also I'm not exactly sure how the 120 ohm resistors actually work, all I know is it stops one side from saturating.
