Abstract
A voltage controlled oscillator (VCO) is described. The VCO includes a plurality of nodes coupled with a plurality of transistors, and a first inductor-capacitor (LC) tank coupled with a second LC tank. The first LC tank and the second LC tank include a shared inductor structure coupled to the plurality of nodes. The first LC tank and the second LC tank each include a capacitor. The capacitors are each coupled on a first side to a node of the plurality of nodes and on a second side to a respective capacitor in the other LC tank. The first LC tank and the second LC tank are configured to resonate at a fundamental frequency for differential-mode signals, and the first LC tank and the second LC tank are configured to resonate at twice the fundamental frequency for common-mode signals.
