Abstract

A voltage-controlled oscillator (VCO) is a pertinent constituent of numerous electronics gadgets in the present era. VCOs are used in a variety of applications, namely frequency synthesizer, function/signal generator, keypad tone recognizer, building of PLL and various other areas. The implementation and analysis of a VCO having high-frequency and low-power dissipation is presented in this study. The design employs current-starving technique, in which the amount of current for each inverter stage is limited. This technique helps to control power consumed by VCO and provides an efficient tuning of VCO oscillation frequency. The presented VCO provides an output frequency ranging from 749.07 MHz to 2.41 GHz when operated at 1.8 V supply voltage and consumes a total power of 1.5 mW. Tanner EDA tools have been used to analyse and implement the VCO design for the 180 nm CMOS technology node.
