Amplifier Circuit using MOSFET Output Stage

Schematic Diagrams      Comments Off on Amplifier Circuit using MOSFET Output Stage

The circuit presented here is amplifier circuit using MOSFET output stages, as a substitute for the output stage based on bipolar transistors. This project is for those who want to experiment with the power MOSFET. Without going into details, the MOSFET has a characteristic sound of vacuum tubes and bipolar… Read more »

50 watt Mosfet amplifier

Schematic Diagrams      Comments Off on 50 watt Mosfet amplifier

The first stage of the 50 watt Mosfet amplifier is a differential amplifier based on transistors Q1 and Q2. Capacitor C8 is the DC input decoupling, C1 R1 limits input current and a capacitor bypasses undesirable high frequencies. The second stage is composed of the pilot phase transistors Q3 and… Read more »
