Analog Front End Circuit. In a radio receiver circuit the rf front end is a generic term for all the circuitry between a receiver s antenna input up to and including the mixer stage. The investigated analog front end offers lower noise and wider dynamic range with compact size compared to conventional architecture.

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. This analog front end circuit including a sampling circuit and an analog to digital converter is operable to sample amplify and convert the analog image signal to a digital image signal.
An operational amplifier affectionately shortened to op amp is a super high gain differential amplifier.
