A three stage Voltage Controlled Ring Oscillator (VCRO) has been designed, analysis and simulated in 50nm CMOS technology by using LT-Spice. The designed circuit proposed a wide tuning range of operating frequency with very low of supply voltage and low power consumption that can be used for various applications. The designed circuit is operated at 0.8V to 1.2V supply voltage to obtain wide operating frequency range which simulated results show range of about 10GHz with minimum frequency of 0.80GHz to 11.64GHz.
