Zusammenfassung:An electronic chip includes a first well having a first PN junction located therein, a second buried well located under and separated from the first well, and a first region forming a second PN junction with the second well. A detection circuit is coupled to the first well and configured to output a digital signal that has a first logic value when a potential difference within the first region is above a threshold and a second logic value when the potential difference within the first region is below the threshold.
