Abstract :
A novel phase-locked loop (PLL) design for the receivers of UHF wireless microphone is presented. The output-frequency range of the proposed circuit is from 800MHz to 1200MHz with 50MHz interval. It can provide nine frequency channels for UHF wireless microphone application. A programmable multi-modulus frequency divider is employed which enables the dividing ratios within 16-24. The proposed PLL circuit is designed based on the TSMC 0.35μm CMOS technology with a 3.3V supply voltage. The feasibility is confirmed with post-layout HSPICE simulations.
