Abstract
A circuit (e.g., implemented as part of a controller area network (CAN) bus receiver includes a pre-amplifier stage having first and second outputs. The circuit also includes a comparator having first and second inputs. The first input is coupled to the first output of the pre-amplifier stage, and the second input is coupled to the second output of the pre-amplifier stage. The comparator includes an input differential transistor pair, a second pair of transistors coupled to the input differential transistor pair in a cascode configuration, and a push-pull output stage coupled to the second pair of transistors.
