Project Overview
The objective of this project was to create a digital-to-analog (DAC) converter using the R-2R ladder circuit. Afterwards, we built an analog-to-digital (ADC) converter using a Successive Approximation Register (SAR). The SAR ADC works by iterating through various binary codes in the DAC to compare with the analog input voltage using a comparator. By using feedback, the SAR ADC essentially does a binary search for the binary code the generates the input analog voltage.

R-2R Ladder Circuit
Due to COVID-19, this lab was done virtually. This is our circuit done in Tinkercad.
