Abstract
An integrated circuit includes a first semiconductor device with an N type region biased by a first terminal and a second semiconductor device with a second region. An N type guard region is located laterally between the N type region of the first semiconductor device and the second region. A P type region is isolated in the N type guard region and is biased by a second terminal. The N type guard region is either electrically coupled to the second terminal through a resistor circuit or is characterized as floating.
