Power MOSFETs are emerging as the device of choice for high-quality power amplifiers because of their speed, reduced need for protection, and falling cost. A low-distortion power amplifier design is presented which includes output stage error correction to reduce the effect of transconductance droop in the crossover region and thus allow

The Clipping The Clipping Mechanism in Mosfet Mechanism in Mosfet AmplifiersAmplifiers The output voltage swing capability and resulting clip point is a result of different parameters than the V ce(sat) induced clipping that occurs in bipolar power amplifiers. There are 2 potentially contributing factors with a mosfet: • R ds(on)

Vertical power MOSFETs (and similar technologies, such as PI and trench types like Toshiba J200/K1530) tend to have a 'sweet spot' where the capacitance, gm and current are sensible enough tp get good performance in audio - usually this happens in MOSFETs with Vdsmax between 100 and 300V - usually on the lower end of this range for P channel …

The shown MOSFET amplifier design circuit will happily output a 35 watts RMS into an 8 ohm load. The total harmonic distortion will not be more than around 0.05%. The prototype was analyzed only for signal frequencies around 1 kHz. However the circuit's open loop gain was found to be practically constant within the entire audio frequency range.

The only change that is needed is to trim the MOSFET bias pot! With the full supply voltage of ±70V (which must not be exceeded!), continuous ('RMS') power is around 180W into 8 ohms, or 250W into 4ohms. Short term (or 'music') power is typically about 240W into 8 …

Hi Dibya, In the sixties and seventies quasi amps were popular because there were very few high power pnp transistors. So using ideas from the 'n' type vacuum tube of the day, quasis were designed and built. They are a very design from the POV of second harmonic; they sound warm, but deliver...
