The efficiency of this amplifier is 70%, distortions at cut frequency were at most 0.2% at 20Hz on 8Ω and 10W. With a power supply of ± 30V the mosfet audio amplifier can deliver 45W on 8 Ω and 70w on ...

In summary, package impedance, PCB layout, interconnect parasitic, and switching speed are all critical factors influencing a MOSFET’s performance in a power-supply circuit. Hence, to get the best ...
