This simple mosfet power audio amplifier circuit, with TL071C and 2 MOSFETs (IRF9530 and IRF530) can deliver up to 45W on 8Ω speaker or 70W on 4Ω speaker. This schematic is based on Siliconix ...
The objective of the project is to create a 2-stage hybrid headphone amplifier where the voltage stage uses a vacuum tube that feeds a MOSFET follower output stage with low voltage while both are ...
The power transistor must be chosen to provide fast response while also withstanding high power dissipation. Several electrical and thermal characteristics must be considered: 1. An array of N current ...
