Abstract :
In this article an ultra low power, low phase noise current starved CMOS VCO are proposed. This CSVCO is applicable for wireless communication such as in RFIC (Radio Frequency Integrated Circuits), wireless transceiver, clock generation and recovery, phase lock loop etc. This proposed circuits area and power consumptions are very less and compatible with wireless devices. It demonstrates the superlative performance of the CSVCO. Transient response and phase noise analysis is performed and after simulation the phase noise at 1MHz is -104.0dBc/Hz and power gain estimation at 2 GHz is -185.8dBm is obtained with supply voltage of 1 V. It is performed using cadence virtuoso gpdk045 nm CMOS technology.
