- VCO / REDUCING MISMATCH CAUSED BY POWER/GROUND ROUTING IN MULTI-CORE VCO STRUCTURE

摘要

Reducing coupling and mismatch in multi-core VCOs is achieved by arranging a plurality of inductors of a plurality of VCO cores in a parallel differential inductor configuration with shared leads to form one node, An inductor and a second inductor; Connecting the power / ground traces from the first side only to the first inductor and connecting the power / ground traces to the second inductor only from a different side than the first side to prevent current loops.
