Analysis of Current Starved Voltage Controlled Oscillator using 45nm CMOS Technology

Aniket Prajapati , P.P.Prajapati

An oscillator is an electronic device that used for the aim of generating a signal or waveform. Applications vary from clock generation in microprocessors to carrier synthesis in cellular telephones, requiring vastly different oscillators, oscillators’ topologies and performance parameters. VCO can be built using many circuit techniques. This paper deals with the design and implementation of Current Starved voltage controlled oscillators (CSVCO) using 45nm CMOS technology. CMOS circuitry in VLSI dissipates less power when static, and is denser than other implementations having same functionality. A VCO is an oscillator, where the control voltage controls the oscillator output frequency. The simulation of CSVCO is done in LT-Spice
