Original Abstract Submitted
A comparator circuit with dynamic hysteresis. A common source branch is configured to conduct a differential current at first and second intermediate outputs responsive to a differential input at first and second inputs, and a common gate branch is configured to generate a voltage at a third intermediate output responsive to the differential current at the first and second intermediate outputs. A hysteresis branch includes a hysteresis current generator including first and second replica transistors having source/drain paths coupled in parallel, and gates coupled to the first and second inputs, respectively. A hysteresis capacitor is coupled between the sources of the first and second replica transistors and the common terminal. Current mirror circuitry is coupled to the source/drain paths of the first and second replica transistors, to supply a hysteresis current responsive to the absence of current conducted by the parallel first and second replica transistors.
