Abstract
A regeneration circuit includes a first inverting circuit, a second inverting circuit, a first transistor coupled to an input of the second inverting circuit, and a second transistor coupled to an input of the first inverting circuit. The regeneration circuit also includes a third transistor including a gate coupled to a gate of the first transistor, a first switch configured to couple the third transistor to the input of the second inverting circuit based on a voltage of the first inverting circuit, a fourth transistor including a gate coupled to a gate of the second transistor, and a second switch configured to couple the fourth transistor to the input of the first inverting circuit based on a voltage of the second inverting circuit.
