ABSTRACT:
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.
