Abstract
A system and a method for voltage-controlled oscillator (VCO are disclosed. A first VCO core includes a first cross-coupled (CC) transistor pair having a first conductivity type and a second cross-coupled transistor pair having a second conductivity type. A second VCO core includes a third CC transistor pair having the first conductivity type and a fourth CC transistor pair having the second conductivity type. A first synchronization trace connects the first CC transistor pair to the third CC transistor pair. A second synchronization trace connects the second CC transistor pair to the fourth CC transistor pair. The first and second VCO cores are arranged on a circular path on a substrate and disposed opposite with each other with respect to a center of the circular path.
