Description
Summary:This paper shows a digitally tunable analogue processing architecture based on an adaptive circuit. The conditioning circuit has been designed to extend the linear range of an angular position sensor, compensating the output drift due to temperature variations. System-level simulations give a temperature-independent linear output in the range of 293-353 K, with an accuracy of 2 degrees in the angular position. Inherent low power and low size characteristics make these circuits valuable to implementing the "smartness" part of smart sensors
