Abstract
A comparator circuit includes a first transistor have a control electrode coupled to a first input voltage, a first current electrode coupled to a second input voltage, and a second current electrode coupled to a first circuit node. The circuit also includes a first inverter coupled to a first voltage supply terminal and having a first input coupled to the first circuit node and an output, a second transistor having a control electrode coupled to the output of the first inverter, and an active resistive element coupled in series between the first circuit node and a first current electrode of the second transistor.
