Abstract
A circuit includes a first digital controlled oscillator and a second digital controlled oscillator coupled to the first digital controlled oscillator. A skew detector is connected to determine a skew between outputs of the first digital controlled oscillator and the second digital controlled oscillator, and a decoder is utilized to output a control signal, based on the skew, to modify a frequency of the first digital controlled oscillator using a switched capacitor array to reduce or eliminate the skew. A differential pulse injection oscillator circuit and a pulse injection signal generator circuit are also provided.
