Systems and methods for measuring current output by a photodetector of a wearable sensor unit that includes one or more magnetometers

Abstract

An exemplary controller may include a single clock source configured to generate a single clock signal used to drive one or more components within a plurality of magnetometers and a plurality of differential signal measurement circuits configured to measure current output by a photodetector of each of the plurality of magnetometers.
