Patent abstract
Circuits, methods, and systems that calibrate or account for packaging and related stress components in a pressure sensor. Further examples provide an improved sensor element or device. One example provides one or more sensing elements on the diaphragm and near the diaphragm-bulk boundary. Sensors near the diaphragm-bulk are used to estimate package-induced stress. This estimation can then be used in calibrating package stress from pressure measurements.
