Abstract
A comparator includes a folded cascode stage having positive and negative outputs. The folded cascode stage includes: a common-mode voltage regulation circuit that includes resistive elements that are respectively situated between each of the outputs and a common-mode node. A compensation circuit is configured to regulate a difference between the voltages on the outputs, and is configured to generate a constant and continuous compensation current in the two resistive elements. A hysteresis circuit is configured to offset voltages on the outputs, and to generate a hysteresis current in the two resistive elements.
