Abstract
Reducing coupling and mismatch in multi-core VCOs, including: arranging a plurality of inductors in a plurality of VCO cores in a parallel differential inductor configuration with shared leads to form a single node, wherein the plurality of inductors includes at least a first inductor and a second inductor; connecting power/ground traces to the first inductor from a first side only; and connecting the power/ground traces to the second inductor from another side different from the first side only to avoid making a current loop.
