Abstract
Quadrature clocking schemes are widely used in modern communications systems, but often suffer from phase imbalance. Conventional solutions that attempt to address this phase imbalance, however, are generally large and use a substantial amount of power. Here, however, a correction circuit is provided that can locally correct for phase imbalance without the need for bulky and high power consuming circuitry.
