US Patent 7151814 Hogge phase detector with adjustable phase output

A system and method are provided for adjusting the phase output of a Hogge phase detector. The method comprises: using a Hogge phase detector, generating a reference signal; using the Hogge phase detector, generating a phase and reference signals; accepting an adjust signal; modifying the amplitude of the phase signal in response to the adjust signal; integrating the amplitude modified phase signal; using the integrated signal as a phase adjusted signal; integrating the reference signal; using the integrated reference signal and phase adjusted signal to generate a voltage controlled oscillator (VCO) signal; at the Hogge phase detector, accepting the VCO signal as the clock signal. Some aspects of the method further comprise: using the VCO signal to sample data at a settled first phase of the clock; changing the adjust signal; and, using the VCO signal to sample data at a settled second phase of the clock.
