Wide-Band Current Starved Ring CMOS Voltage Controlled Oscillator (VCO) using 0.18 μm CMOS Technology
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 5
Abstract
This paper describes a design and implementation of Current Starved CMOS Voltage Controlled Oscillator based on Ring Oscillator. Efforts are made to design a CMOS Voltage controlled oscillator having wide frequency range with High frequency, Low power. So, the CMOS VCO designed here having a Five Stage Current Starved CMOS VCO and Seven Stage Current Starved CMOS VCO. The design is optimization and simulates on TSMC 180nm CMOS process at 1.8 V supply voltages. The Five Stage CS VCO results show that the oscillation frequency of VCO varies between 18.724MHz to 1890.4MHz and power consumption may varies between 35.39 µW to 25.013 µW and the Seven stage CS VCO results show that the oscillation frequency of VCO varies between 68.971MHz to 2099.5 MHz and power consumption may varies between 2.59 µW to 348.81 µW.
