The mixed signal system only requires the digital processor to be active at the time of weight updates in the analog adaptive filter, minimizing the overall power consumption. Further, the proposed system uses a lesser number of ADC than a digital processor. The brain is adapted from “Human Brain.png” by Injurymap, Wikimedia Commons, CC BY 4.0. Modifications were made.
