Abstract
In one embodiment, a voltage-controlled oscillator (VCO) is provided that includes: a plurality of differential inverter stages coupled to form a loop, each differential inverter stage having including a switched capacitor circuit configured to control a signal delay through the differential inverter stage responsive to a control circuit, whereby an output frequency for the VCO is inherently compensated against changes in semiconductor process variations and thermal variations.
