Vol 7, No 2 (2022): Design of Low Power CMOS LC VCO Using Nm Technology

Authors:-Priyanka Meathil, Jitendra Ahirwar

Abstract:- In this paper, a Low power CMOS LC Voltage Controlled oscillator for C band has been designed. The cross coupled differential LC VCO topology is used to optimize the trade- off between the phase noise and power consumption. A 70nm CMOS technology has been used for wireless applications. To achieve high frequency tuning range a variable MOS capacitance has been used by varying gate voltage of MOS in order to meet this VCO topology for C band applications. Simulation is performed by Tanner EDA 14.0 on 70nm CMOS technology. The tuning frequency of the LC VCO circuit is from 4.99 to 5.38GHz this can obtain by applying the tuning voltage ranging from 1.5 to 2.7 V. This topology dissipates power of 1.40mW at the Maximum oscillation frequency which is very low as compare to conventional VCO. 

Keywords:- Voltage Controlled oscillator (VCO), tuning frequency, tuning range, power consumption, CMOS.
