A Tunable Analog Conditioning Circuit Applied to Magnetoresistive Sensors

This paper presents an adaptive processing system based on analog-digital circuits to extend the linear range of angular position sensors compensating the temperature-dependent drift. System-level simulations give a sensor output improvement higher than 70%, which drastically reduces deviations due...

Description
Summary:This paper presents an adaptive processing system based on analog-digital circuits to extend the linear range of angular position sensors compensating the temperature-dependent drift. System-level simulations give a sensor output improvement higher than 70%, which drastically reduces deviations due to temperature. The building block architecture characteristics make these circuits suitable for implementing the ldquosmartnessrdquo part of smart sensors in embedded systems.
