Abstract
A voltage-controlled oscillator (VCO) is disclosed that includes an inductor-capacitor (LC) tank coupled with a first voltage supply node, a pair of cross-coupled transistors that are coupled with the LC tank and coupled with each other at a tail node, and a high-frequency current return path to the first voltage supply node. The high-frequency return path includes a first decoupling capacitor coupled with the first voltage supply node and a second voltage supply node, and a first inductor coupled with the tail node and the second voltage supply node. The first inductor is formed as a first conductive trace and has a quality factor (Q) value of 25 or greater.
