Mechanical stress, as one of the physical quantities of potential interest, provides various information from simple static to dynamic load. Integration of piezoresistive elements within a complete CMOS system has been achieved in many ways, and ground-laying effects have been studied and described in detail. To bring the mechanical and electrical domains closer together, a new concept is presented that allows an analytical and simulation-based approximation of the sensors’ behavior due to applied mechanical stress as part of established concepts in electronics. It is evaluated based on measured state-of-the-art sensor implementations and used to bring up an alternative architecture with enhanced and on-the-fly adaptive sensitivity. Simulations are used to then further evaluate any model errors due to second-order effects that have been neglected within the design process.en1549-832820242583594Institute of Electrical and Electronics Engineers Inc.adjustable current mirrorintegrated sensingPiezoresistancepiezoresistivitySensitivitysensor modelSensorsSensor systemsStrain measurementStressTransducersTransistorsEngineering and Applied OperationsJournal Article10.1109/TCSI.2023.3339224Journal Article
