A New Technique for the Design of Multi-Phase Voltage Controlled Oscillators

Abstract

In this work, a novel circuit structure for second-harmonic multi-phase voltage controlled oscillator (MVCO) is presented. The proposed MVCO is composed of N (N being an integer number and N 2) identical inductor–capacitor (LC) tank VCOs. In theory, this MVCO can provide 2N di®erent phase sinusoidal signals. A six-phase VCO based on the proposed structure… (More)
