CMOS Frequency Generation System for W-Band Radars

 

Abstract

A W-band CMOS frequency generation system, including a phase-locked loop (PLL) (55-60 GHz) with a frequency-divided-by-2 output and an offset mixer for generation of a W-band carrier (83-90 GHz), is realized using low leakage transistors of a low cost 65-nm bulk CMOS process. The phase noise of PLL is as low as -87 and -112 dBc/Hz at 1 and 10 MHz offsets. The PLL consumes 46 mW. The total frequency generation system consumes ~180 mW.
