Abstract
An electronic chip includes a doped semiconductor substrate of a first conductivity type, a doped buried layer of a second conductivity type overlying the substrate, and a first doped well of the first conductivity type overlying the buried layer. Circuit components can be formed at a top surface of the first doped well and separated from the buried layer. A current detector is coupled to the buried layer and configured detect a bias current flowing into or out of the buried layer.
