From Silicon to Signal: The Hidden World of Analog Front-End (AFE) Design

Analog Front-End (AFE) design bridges physical signals and digital systems through low-noise op-amps, filters, and ADCs. Engineers face trade-offs in noise, power, resolution, and cost while ensuring signal integrity and noise immunity. From biomedical ECGs to automotive ADAS and industrial monitoring, AFEs underpin safe, accurate, and scalable sensing in modern electronics.
