Abstract :
This paper presents a study of mismatch effects in a digitally programmable analogue processor designed for small embedded applications. Circuit programmability allows for its adaptation to deviations in circuit operation or environmental effects. Starting from circuit simulation data, the system-level operation is modelled, showing its robustness to circuit mismatch. Simulation results of the proposed processor applied to compensate the response of a sinusoidal sensor and its robustness to mismatch are presented.
