Mosfet Power Amplifier Circuit

Published:2011/7/1 3:35:00 Author:Joyce | Keyword: Mosfet, Power Amplifier | From:SeekIC

As shown in the figure is a power amplifier circuit consisting of MOSFET tube.The second differential motion in the circuit uses medium power MOSFET 2SJ77 , and the current mirror circuit uses 2SK214. The working current is 6 mA. Since the voltage of power supply is high( ±50V), the transistor will get hot, so a small radiator should be connected.
