This paper presents a new design approach of CMOS voltage controlled oscillator (VCO) with low power and wide frequency tuning range. A novel current starved delay cell has been proposed based on dual delay path architecture. The results have been obtained in 45 nm CMOS technology with supply voltage 1 V. The proposed VCO achieves a controllable frequency range from 1.81 GHz to 10.55 GHz with a wide tuning range. The control voltage (Vctrl) has been varied from 0.3V to 1V for obtaining the different output frequencies. The power dissipation of proposed VCO is 34.932 uW with current consumption as 0.079 mA at a control voltage of 1V and very optimised surface area as 14.8µm2. Keywords: Current starved delay cell, Low Power, Tuning range, VCO, etc.
