Webrequired (i.e., it is quasi class A in that the operating point movement is minimal). Simply by decreasing the Icq of the amplifier by a small amount, Class AB operation can be reached. But any Class AB single-ended power amplifier will create more output distortion than a Class-A type due the output clipping of the signal’s waveform. WebThe main goal of a MOSFET amplifier, or any amplifier for that matter, is to produce an output signal that is a faithful reproduction of its input signal but amplified in … WebThe TDA7850 is a breakthrough MOSFET technology class AB audio power amplifier in Flexiwatt 25 package designed for high power car radio.

WebAug 7, 2024 · If you however use some feedback then you can make it linear... like using an op-amp. Most modern op-amps, especially those of modest specifications, will be MOSFET-based, if you just make a feedback with resistors then the amplification will be linear, which is what you want, and then it will work nearly identical to the class B amplifier. WebOct 15, 2013 · By having a low bias current and high R1 and R2 values, the output peak voltage will be lowered. I made this formula to calculate output peak voltage vs. R1 and R2 values: VRL= (Hfe*RL (10Vs-7))/ (10 (Hfe*RL+Rb)), where VRL is the load voltage, RL is the load resistance and Rb is the biasing resistor values.
