Entry 1: Audio amplifier - EE MOD 3 2018-2019

This project is still one of my favorates. Mainly because you produce a tangiable object that actually does something "useful". The project revolves around building an amplifier using a 10 Volt rail and transistors. In our case, this is done by using a class A amplifier to generate a 8V peak to peak from the low energy input audio. Thereafter, amplifying the current using a AB-class amplifier. Here, i have solely designed the entire A-class part and helped to build the AB-class as well. Having done most of the designing (A-class) using LT-spice in a trail and error fashion the SSEQ and biasing calculations where still to be done. This wasnt easy as I had devoloped quite an unconventional way of amplifiying the signal. Using 2 CCC-CEC combinations 100mV input is converted to an 8V peak to peak signal. In the end i did manage to calculate everything through and happened to learn a lot about Bipolar Junction Transistors, and their impact on a circuit.
I have done this project with Tom Brunning and Emilio cuertez in order to finish Module 3 of Electrical Engineering on the University of twente.
