Improved input Mosfet Output Audio Power Amplifier.
This is a class AB audio power amplifier using a differential input stage, a voltage amplifier stage (VAS), and a complementary MOSFET output stage powered by ±29 V.
The differential pair provides input balance and feedback control; the cascode and active load enhance gain, linearity, and bandwidth.
The VAS supplies high voltage gain with Miller compensation for stability.
A bias network sets the quiescent current for smooth class AB operation.
The MOSFET output stage delivers current to the load with excellent thermal stability, fast response, and low distortion.
Global negative feedback ensures flat frequency response and accurate signal reproduction.
Overall: a high-fidelity, thermally stable, wide-bandwidth amplifier with low distortion and clean, dynamic sound.
