Abstract
A comparator includes a first stage including a first output to generate a first output signal that transitions between an upper and lower voltage level in response to a comparison of first and second inputs of the first stage. A second stage includes an input coupled to receive the first output signal from the first output of the first stage, and a second output configured to generate a second output signal in response to the first output signal. A clamp circuit includes a first node and a second node. The first node is coupled to the first output of the first stage and the second node is coupled to a supply voltage. The clamp circuit is configured to clamp a voltage difference between the first node and the second node to clamp a voltage swing of the first output signal.
