Design of Current Starved Mode based Ring Voltage Controlled Oscillator in 180 nm Technology

Abstract

This paper belongs to current starved based single ended ring voltage-controlled oscillator (RVCO) for Phase locked loop (PLL) and other applications. The designed circuit was simulated using SCL PDK 180 nm technology in cadence virtuoso. Designed circuit provides stable oscillation frequency and simulated at supply voltages of 1.8 V for different control voltages of 1.8 V, 1.5 V and 1 V. With respect to the supply voltages tuning range was obtained in the range of 1.09GHz to 3.22 GHz. And phase of the designed ring VCO is - 83 dBc/Hz, -84 dBc/Hz and -90 dBc/Hz with respect to the supply voltages of 1.8 V, 1.5 V and 1 V respectively. The power dissipation of designed VCO at 1.8 V was found to be 0.695 mW.

Keywords: Phase locked loop, voltage-controlled oscillator (VCO), oscillation frequency, phase noise, power dissipation etc.
