<hr>
<p>I design a 180nm CMOS technology operational amplifier capable of over 80dB of gain and 35MHz of bandwidth. Additionally, ample phase and gain margins ensure closed-loop stability. This project was part of UCSD's ECE 164 class during fall 2022.</p>
<br>
<p>The circuit combines a folded cascode and common source amplifier stage to realize high overall gain. Moreover, margin performance was tunable with a compensation resistor and capacitor. Lastly, all MOSFETs were biased with a constant-transconductance reference circuit whose output current was mirrored downstream. Gate voltages were biased with ratiometrically with stacked MOSFET arrangements. Design performance was verified in Cadence Virtuoso. </p>
<br>
<p>Six groups were chosen out of roughly 50 to present their designs in front of a panel of Apple engineers. I was awarded the 2nd place prize: an Apple Watch! Though my performance was not the absolute best, the judges saw merit in my design methodology. Thanks, Apple!</p>
