An analog front-end (AFE or analog front-end controller AFEC) is a set of analog signal conditioning circuitry that uses sensitive analog amplifiers, often operational amplifiers, filters, and sometimes application-specific integrated circuits for sensors, radio receivers, and other circuits to provide a configurable and flexible electronics functional block needed to interface a variety of sensors to an antenna, analog-to-digital converter or, in some cases, to a microcontroller.
A radio frequency AFE is used in radio receivers, known as an RF front end.[1]
