Abstract

A 3-stage single-ended ring oscillator (SERO) based voltage controlled oscillator (VCO) has been proposed to operate from 2,4 GHz to 5,42 GHz for short range wireless communication systems, such as Wi-Fi, Bluetooth and Zigbee. Single-ended delay cell has been adopted to form the proposed VCO in standard 0,18-μm CMOS process. This VCO consumes only 664,51 μW of power. To achieve wide tune range of 55,72%, control voltages are varied from 0,7 V to 1,8 V. The post-layout simulation result of phase noise is -107,59 dBc/Hz at 1 MHz offset from the centre frequency of 4,3 GHz. The circuit is designed and simulated using Mentor Graphics environment.
