Abstract
Circuits and methods for reducing and cancelling out kickback noise are disclosed. In one example, a circuit for a comparator is disclosed. The circuit includes: a first transistor group, a second transistor group, and a first switch. The first transistor group comprises a first transistor having a drain coupled to a first node, and a second transistor having a source coupled to the first node. Gates of the first transistor and the second transistor are coupled together to a first input of the comparator. The second transistor group comprises a third transistor having a drain coupled to a second node, and a fourth transistor having a source coupled to the second node. Gates of the third transistor and the fourth transistor are coupled together to a second input of the comparator. The first switch is connected to and between the first node and the second node.
