Objective: This research paper presents a review on performance comparison of different types of Voltage Controlled Oscillators to analyze power dissipation and frequency response. Methods: Designs from Ring Oscillator, Current Starved VCO, VCO with gates of PMOS transistors grounded, VCO with PMOS transistors as diode connected load, VCO with Source voltage applied to both PMOS and NMOS transistors and VCO with NMOS transistors as diode connected load are designed on 45nm CMOS Technology using Cadence Virtuoso Tool. Findings: The performance of different circuits as Transient response, Frequency Response, Stability, Power has been comparatively analyzed through different simulations. Current Starved VCO is concluded as most linear design. All design procedures, Circuit and simulation results are illustrated.
Keywords: Current Starved VCO, Cadence Virtuoso, 45nm CMOS Technology, NMOS Transistors as Diode Connected Load, PMOS Transistors Grounded, PMOS Transistors as Diode Connected Load, Source Voltage on PMOS and NMOS Transistors
