Embodiments of the disclosure provide a differential clock duty cycle correction (DCC) circuit, including: a hybrid current injector including current sources for generating a correction current, wherein the correction current is added to a clock signal of a first polarity at a first correction node and subtracted from a clock signal of an opposite polarity at a second correction node, and wherein a plurality of the current sources in the hybrid current injector are controlled by a first portion of a n-bit DAC code to generate the correction current; and a current DAC for receiving a second, different portion of the n-bit DAC code and for outputting a corresponding reference current to the current sources in the hybrid current injector, wherein the current sources generate the correction current in response to the reference current output by the current DAC for the second portion of the n-bit DAC code.
