Abstract :
The feasibility of a low cost, 2.5 Volts supply phase-locked loop (PLL) for HomeRF application is demonstrated. Based on IEEE 802.15.4 specification, this PLL is used in a STMicroelectronics propriatory system to achieve both frequency synthesis and frequency shift keying (FSK) modulation. Simulation results of the PLL and the open loop modulation together with VCO measurements are presented. All the circuits have been fully integrated using STMicroelectronics 0.28 mum CMOS technology.
