Abstract :
Two kinds of integrated circuit are described for use in FM demodulators of satellite TV receivers. The ICs, an automatic gain control amplifier (AGC AMP) and a phase-locked demodulator, include a signal level amplifier, a driver for the first AGC circuit, an automatic frequency tuning amplifier, and a voltage regulator. The ICs were fabricated using an advanced nitride self-aligned process with 2-μm design rules. The threshold level, the differential gain, and differential phase of the FM demodulator using those ICs are 6 db, 1%, and 1°, respectively.
