Abstract

A frequency synthesizer incorporating one single-sideband (SSB) mixer generates seven bands of clock distributed from 3 to 8GHz with 1-ns switching time. An efficient frequency synthesizing technique producing balanced bands around one center frequency is employed, and the SSB mixer uses double degeneration topology to increase the linearity. Fabricated in 0.18-μm CMOS technology, this circuit achieves a sideband rejection of 37 dB while consuming 48 mW from a 2.2-V supply.
