Abstract :
This paper demonstrates the possibility of reducing circuit complexity in an AM-FM radio by replacing the FM-IF amplifier limiter and detector as well as the audio preamplifier, with a monolithic linear integrated circuit, the ??A717. The unconventional circuitry of the FM detector and low-voltage power supply and the elimination of audio switching between FM and AM operation are discussed in detail. The performance figures of the complete radio are given.
