Web5 jan. 2024 · A Class AB Power Amplifier is, as the name suggests, a mix of Class A and Class B power amplifiers. Like the Class B amplifier, it also uses 2 conducting elements (transistors), but they both run at the same time. This eliminates the ‘dead zone’ from -0.7 V to + 0.7 V seen in the Class B power amplifier. Web13 jul. 2024 · Fig.1 — CMOS Differential Amplifier Circuit. All MOSFETs are in saturation. Also, we can see from the circuit that MOSFETs 3 and 4 act as a current mirror, hence are of the equal dimensions.

WebIn addition, most MOSFETs have an output protection diode which allows utility comparable to a BJT in switching inductive loads such as relays and motors. Along the same lines, the MOSFET retains its amplification char acteristics much closer to its turn -off and saturation point s than does a BJT.
