This paper explains the design and simulation of a conditioning circuit based on a current-mode mixed analogue-digital adaptive processor. The proposed processor model consists of two main blocks: a D/A four quadrant multiplier and a current conveyor that performs the non-linear output function. Applied to sensors conditioning, the processing system customizes its free parameters, stored in digital registers, adapting the response. System simulation results and achieved performance are presented.
