Abstract
A linearity compensation circuit is disclosed for improving the linearity of a sensing signal. The linearity compensation circuit may include a compensator that is capable of receiving a sensing signal from a sensor and generating a compensation signal based on the sensing signal. The linearity compensation circuit may also include an output circuit that is capable of combining the compensation signal and the sensing signal to generate a compensated signal that exhibits an improved linearity. Also disclosed is a sensing apparatus which includes a sensor and the linearity compensation circuit. The sensing apparatus may thus be able to generate a sensing signal that is linear over a wider dynamic range.
