Abstract
A low power comparator circuit is provided. The circuit includes a comparator core including a first stage. The first stage has an output configured to provide a digital value. A capacitor includes a first terminal coupled at an input of the first stage and a second terminal selectively coupled to a first input and a second input of the comparator core. A voltage generator is coupled to the first stage. The voltage generator is configured and arranged to generate a first voltage based on a predetermined input current and to limit a maximum current of the first stage based on the predetermined input current.
