Abstract :
We have developed a carmlete single chip AM/FM radio integrated circuit embodying all the necessary function for an AM/FM radio system. It includes the AM/FM front end, AM/FM IF amplifiers, AM AGC, AM/FM detector, audio pre and power airplifiers, variable capacitor diode for the FM AFC, tuning indicator circuit, electric volume, as well as a regulated supply. As a result, the application of this IC enables a complete AM/ FM radio system without any use of active ccmponents.
