Varactorless Dual Band Voltage Controlled Oscillator (VCO) for V-band Application

Abstract

In this paper design and modeling of the dual band technique using transformer is described for V-band Voltage Controlled Oscillator (VCO). VCO has been designed and simulated for dual band operation using an octagonal transformer with two MOS switches as a tunable element in UMC 130 nm single poly eight metals (1P8M) technology. Under 1V supply VCO can be tuned for 51.6 GHz to 64.6 GHz. Phase noise at 10 MHz offset from 64.6 GHz carrier is -116.5 dBc/Hz, while the power dissipation is 6.32 mW. The Proposed VCO achieves the calculated Figure of Merit (FoM) of -184.69 dBc/Hz and provides wide frequency tuning with acceptable low phase noise for V band application.
