Concept for compensating the influence of external disturbances on physical function parameters of integrated circuits

摘要

Circuit (150; 200) for generating an output signal (116) which depends on a physical useful variable (108), having the following features: a device (106) for detecting the physical useful variable (108), the device (106) for detecting is arranged to generate an output signal (116) which is based on the physical useful variable (108), a control signal (112) for the device (106) for detection, and an unchanged control signal (112) from an external disturbance variable (118 '; 118, 119) depends; a sensor device (120) for detecting the external disturbance variable (118 '; 118, 119) and for supplying a sensor signal (122) which depends on the external disturbance variable (118'; 118, 119); and means (124) for processing the sensor signal (122) in order to influence the control signal (112) as a function of the sensor signal (122) so that the influence of the external disturbance variable (118 '; 118, 119) on the output signal is reduced ; the circuit further comprising a memory (152) configured to store information on ...
