Abstract
A voltage controlled oscillator (VCO) having a harmonic trap is disclosed. A VCO includes first and second transistors cross-coupled with one another. The VCO further includes a first inductor having first and second loops coupled to one another, wherein the first inductor is arranged such that current flow through first loop is in the opposite direction of current flow in the second loop. The VCO further includes a second inductor that implements a third loop surrounding the first inductor.
