Abstract:
Abstract: Voltage Controlled Oscillator is a predominant block in VCO-based sigma-delta analog to digital converter. A seven-stage hybrid VCO is designed to generate a high frequency of oscillation, full voltage swing, at low power consumption. The frequency of oscillation achieved for seven-stage hybrid VCO is 2.05 GHz with a low power dissipation of 144μW and output voltage swing of 1.15 V. The output noise for Hybrid VCO at 1MHz of offset frequency is 492nV/sqrt(Hz). It is pertinent to mention here that to justify the performance, robustness, scalability, and reliability worst-case analysis is considered and corner variations are performed with 500 runs of Monte Carlo simulation. The proposed hybrid VCO is designed and implemented using a cadence virtuoso platform of 0.09μm technology for a supply of 1.2V. Keywords: Phase Noise, Output Noise, Low Power, and Eye Diagram
