    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.

    Based on the schematic of a famous Swiss made power amplifier (Goldmund Mimesis3), I did some little modifications on each stage according to my personal taste. After a long listening, testing and did some changes (tweaking) as well as an understanding of the sound character (a little research and trial), then as the end result, I put it in the design which now …

    Figure below exhibits the circuit diagram of a functional 35 watt power MOSFET amplifier circuit. Except the MOSFET's application in the amplifier's output stage, everything basically looks quite like a very common MOSFET amplifier design. Tr1 is rigged as a common emitter input stage, directly connected to the Tr3 common emitter driver stage.

Project 101 - High Fidelity Lateral MOSFET power amplifier

    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 …
