Amplifiers + jfet test pcb

Project Overview

Complete PCB with all circuits for Audio 1 and Power Electronics @Vives Kortrijk. With a printable base for better stability and preventing short circuits. The base uses heated inserts (M3) for mounting the PCB.

The PCB contains a Class A amplifier in two-stage configuration with Darlington output. Additionally, there's a Class AB amplifier with push-pull configuration and diode bias operating on dual supply voltage. For frequency analysis, there are two circuits: a BJT common emitter configuration and a JFET common source configuration, both with bypass options. All important signals are accessible via test points and connectors. Design Image
