Abstract

A method for differential buffer phase correction comprises generating a pair of differential signals from a local oscillator, applying one of the signals to a first inverter and the other signal to a second inverter of a buffer through a differential pair of lines, applying a first positive feedback signal to the first inverter through a first feedback capacitor, wherein the first positive feedback signal is generated from an output of the second inverter and applying a second positive feedback signal to the second inverter through a second feedback capacitor, wherein the second positive feedback signal is generated from an output of the first inverter.
