Abstract
Most sensors and actuators require calibration and linearization before they can be used reliably in a measurement or control system. Often digital signal processing is used for this. As an alternative, a bipolar analog signal processing circuit is presented which can be used to program offset, gain, second and third order non-linearity of a transducer with an 8-bit accuracy, while maintaining a large analog signal bandwidth. INTRODUCTION Most transducers require calibration and linearization before they can be used reliably in a system. Often the microcontroller in the system is used to compute correction curves for each transducer, and each signal sample is passed through a digital correction formula. This demands system computation power and implicates a much slower signal processing, especially in systems with multiple transducers. This problem is often tackled by using high-speed DSP. This abstract describes an alternative solution in the form of an analog circuit dedicated for c...
