Sample and Average Common-Mode Feedback in a 101 nW Acoustic Amplifier

Kyojin Choo

We present a Sample and Average Feedback Resistor (SAFR) for accurate and programmable common-mode feedback in capacitively coupled low-power amplifiers. Using only switches, clocks, and capacitors, we reduce the variation across process and temperature by ...
