Week 5, 10 Sep

This week, I focus myself on building the voltage inverter circuit.

The voltage inverter circuit takes in 3.3V from the other power supply circuit board, and invert it to produce -3.3V. The inverted voltage is then fed into negative terminal of power supply of an amplifier.

Below is the schematic diagram.


Here is the PCB board that I made for temporary testing purposes.
