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.
