Abstract

Conventional PLL FM demodulators require large capacitors in the loop filter in order to provide a con- trolled loop response. For an integrated demodulator, the large loop filter capacitors must be provided as exter- nal parts. This adds to the parts count of a radio and thus increases its cost and manufacturing time.
