Abstract

This paper describes the design of a fully integrated phase-locked loop frequency synthesizer intended for use as the local oscillator in a mobile telecommunication receiver or transmitter. The design of some key blocks is discussed in more detail. These include a 64/65 dual modulus prescaler having a maximum input frequency of 2.4 GHz and a power dissipation of 7.3 mW, 10-bit programmable dividers for VCO and crystal reference frequencies, a phase detector and a chargepump, an integrated passive loop filter, and a balanced voltage-controlled oscillator having a tuning range from 1.8 to 2.2 GHz
