deliver single digit voltage gains. Even though calculating the gain for a MOSFET amplifier design is a well understood exercise, designing a MOSFET amplifier for a specified, moderately high gain at the outset is not. This is because the gain parameter of a MOSFET, its transconductance, is both a function of, and interacts with, its bias point.

MOSFET Amplifier Example No1. An common source mosfet amplifier is to be constructed using a n-channel eMOSFET which has a conduction parameter of 50mA/V 2 and a threshold voltage of 2.0 volts. If the supply voltage is +15 volts and the load resistor is 470 Ohms, calculate the values of the resistors required to bias the MOSFET amplifier at 1/3(V DD). Draw the circuit diagram.

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 MJR7-Mk5 LATERAL MOSFET CLASS-AB POWER AMPLIFIER. Tested at 4V into a 7R5 load to check for crossover effects the 1kHz distortion was mostly second harmonic under -120dB (0.0001%), achieved with only 100mA quiescent current. Power output is around 30W into 8ohms with a single 60V supply, or higher voltages can be used for up to about 100W.
