A voltage controlled oscillator (VCO) applied to phase‐locked loop with multi‐node coupling triple mode redundancy is proposed in this Letter. The proposed VCO consists of three independent operating VCOs. These VCOs are coupled through a metal oxide metal capacitor to synchronise the output of the three independent VCOs. The proposed VCO does not introduce loop delay, and the frequency and phase noise do not decline.
