Abstract :
This paper describes the design of a low power 1.8GHz fully integrated phase locked loop based frequency synthesizer. The synthesizer includes a conventional tristate phase frequency detector, a fully differential charge pump, a 2nd-order on-chip loop filter, a voltage-controlled ring oscillator and an integer-N multimodulus divider. The synthesizer is implemented in a 0.13μm CMOS process and consumes less than 3.5mW of power at a supply voltage of 1.2V. The entire synthesizer is designed using current mode logic and occupies an active area of 0.34mm2
