Abstract :
A fully integrated 0.13mum CMOS ring-oscillator-based PLL for low-IF single-chip DBS satellite tuner-demodulator IC is presented. A noise-attenuating loop filter reduces the oscillator gain, helping both front-end noise and spur rejection and allowing the on-chip integration of the filter capacitance. The PLL shows <1.5degrms double-sided integrated phase noise, <-60dBc reference spurs, <-50dBc coupled spurs. It occupies 0.3mm2 die area and consumes 40mA at 3.3V
