Abstract
An integrated circuit includes a first field effect transistor (FET) and a second FET formed in or over a semiconductor substrate and configured to selectively conduct a current between a first circuit node and a second circuit node. The first FET has a first source, a first drain and a first buried layer all having a first conductivity type, and a first gate between the first source and the first drain. The second FET has a second source, a second drain and a second buried layer all having the first conductivity type, and a second gate between the second source and the second drain. A first potential between the first source and the first buried layer is configurable independently from a second potential between the second source and the second buried layer.
