Abstract: A phase detection circuit can include two phase detectors that each generate a non-zero output in response to input signals being aligned in phase. The input signals are based on two periodic signals. The phase detection circuit subtracts the output signal of one phase detector from the output signal of the other phase detector to generate a signal having a zero value when the periodic signals are in phase. Alternatively, a phase detector generates a phase comparison signal indicative of a phase difference between periodic signals. The phase comparison signal has a non-zero value in response to input signals to the phase detector being aligned in phase. The input signals are based on the periodic signals. An output circuit receives the phase comparison signal and generates an output having a zero value in response to the periodic signals being aligned in phase.

Abstract: High resolution output drivers having a relatively small number of sub-driver branches or slices each having nominal impedances substantially larger than a quantization step and that incrementally differ from one another by an impedance step substantially smaller than a quantization step. In one implementation, such "differential" or "non¬ uniform" sub-driver slices implement respective elements of an n choose k equalizer, with each such differential sub-driver slice being implemented by a uniform-element impedance calibration DAC. In another implementation, each component of a uniform-slice equalizer is implemented by a differential-slice impedance calibration DAC, and in yet another implementation, each component of a differential-slice equalizer is implemented by a differential-slice impedance calibration DAC. In an additional set of implementations, equalization and impedance calibration functions are implemented bilaterally in respective parallel sets of driver branches, rather than in the nested "DAC within a DAC" arrangement of the hierarchical implementations. Through such bilateral arrangement, multiplication of the equalizer and calibrator quantizations is avoided, thereby lowering the total number of sub-driver slices required to meet the specified ranges and resolutions.
