Abstract
A circuit includes an NMOS transistor having a drain and a source, a p-well containing the drain and the source, an n-well under the p-well, and a first well switch configured to selectively connect the n-well to a predetermined voltage in response to an enable phase of a first switching signal. The first well switch can be configured to connect the n-well to the predetermined voltage during the enable phase of the first switching signal and to electrically float the n-well during a non-enable phase of the first switching signal.
