Abstract
This disclosure is directed to a Voltage-Controlled Oscillator (VCO) with reduced phase noise compared to other VCOs. The VCO may include a first cell and a second cell separated by common-mode (CM) isolation circuitry. The first cell and the second cell may each include a portion of the CM noise of the VCO. Moreover, gate terminals of switches of the first cell and the second cell may be cross-coupled to drain terminals of the switches of the second cell and the first cell respectively. An interdependency of voltages of the first cell and the second cell may reduce an amplitude of the respective portions of the CM noise on the first cell and the second cell.
