Robust Adaptive Electronics for Sensor Conditioning

This paper presents a study of mismatch effects in a digitally programmable analogue processor designed for sensor output conditioning in embedded applications. System adaptability allows for its adjustment to deviations in circuit operation or environmental effects. Starting from electrical simulation data, the system-level operation is modeled. Simulating the operation of a processing architecture based on the proposed processor, applied to compensate the response of a sinusoidal sensor, its robustness to mismatch is presented.
