Abstract :
A PLL frequency synthesizer with frequency presetting is implemented in a 0.35mum CMOS process and occupies 0.4mm2. The output frequency is between 560 and 820MHz, the supply is 3.3V, the measured settling time is <10mus and the phase noise is -85dBe/Hz at 10kHz offset. The synthesizer can automatically compensate for frequency variation with temperature
