This paper has shown that it is possible to perform effective response compensation of sensors using analog adaptive filter techniques. The case is illustrated by showing how the response of a load cell can be improved to speed up the process of measurement. The load cell is a sensor with an oscillatory output in which the measurand contributes to the response parameters. Thus, a compensation filter needs to track variation in measurand whereas a simple, fixed filter is only valid at one specific load value. It has been shown that the state-variable biquadratic filter provides an accurate and flexible sensor and adaptive compensation filter models. To allow a practical implementation of the adaptive techniques, a novel piecewise linearization technique is proposed in order to vary a floating voltage-controlled resistor in a linear manner over a wide range. Simulation and experimental results are presented, thus showing the viability of the proposed techniques.
