8-bit Digital-to-Analog Converter (DAC) with a Buck Converter

This was a final project for ECE4530 (Analog Integrated Circuit Design). More detailed information coming soon!

We used an R/2R DAC and a Buck Converter to drive a small speaker. Instead of making this on a chip (and so then modeling it on Cadence), we made it on a breadboard. The goal was to mill the PCB (one of my group members had access to and knew how to work a small PCB mill the school had), but the machine broke a few days before the due date.
