摘要： A differential threshold voltage level detection circuit receives a differential voltage pair as an input, applying each component of the differential pair to an individual voltage shifting circuit. Each voltage shifting circuit is configured with a regulated current producing a shifted and a non-shifted version in-phase. For a shifted set of output differential voltages, the shift magnitude is proportional to the current entering a shifting circuit and is configured to be less than a peak-to-peak magnitude of the differential voltage to be detected. A current mirror within the detector contains a current reference configured to produce a current to be passed through a voltage generator. The current magnitude is sufficient to generate a regulated voltage output to the two current regulating devices that supply the voltage shifting circuits. An overlap detector receiving both differential voltage pairs produces a signal indicating an input is at a detection threshold.

摘要： A bias current is generated for an unbalanced differential pair that is proportional to the transconductance gain of the differential pair. When the transconductance gain varies (e.g., due to temperature variations), the bias current varies in proportion thereby maintaining a constant offset voltage. In some implementations, a voltage to current converter circuit generates the bias current from a constant reference voltage that is independent of temperature and voltage supply variations (e.g., a bandgap reference voltage).

摘要： Embodiments of a proportional phase comparator and method for aligning digital signals are generally described herein. In some embodiments, circuitry to align digital signals comprises a proportional phase comparator that generates triangular-shaped pulses for application to a charge pump. The triangular-shaped pulses may reduce an amount of charge injection in the charge pump close to convergence.
