It is given as. gm = Delta (ID) / delta (VGS) (2) To produce the desired gain three potential divider biased circuits were cascaded in series and the total gain is the product of the gains of individual stages. Total Gain = A1*A2*A3 (3) Where, A1, A2 and A3 are the gains of first, second and third stage respectively.

So, as per the formula, the output of the power amplifier at 4 Ohms load is. Amplifier Wattage = 20.9 2 / 4 Amplifier Wattage = 109.20 (more than 100W approximately) Things to Remember while Constructing 100w audio Amplifier. When constructing the circuit, MOSFETs are needed to be connected with the heatsink properly at Power amplifier stage.
Project 101 - High Fidelity Lateral MOSFET power amplifier
https://sound-au.com/project101.htm
The schematic of the amp is shown in Fig. 1, and it is about as simple as a high power MOSFET amplifier can get - it is considerably simpler than most, but lacks nothing in performance. The circuit diagram belies the ability of the amplifier though, so do not be tempted to think that it cannot perform as well as more complex designs - it does, and exceeds the performance of …
