Methods and apparatus for an analog rotational sensor having magnetic sensor elements

摘要

Methods and apparatus for a sensor include a signal generation module including a first magnetic sensor to generate a first waveform in the form of a sine wave and a second magnetic sensor to generate a second waveform in the form of a cosine wave, the first and second waveforms containing angular position information of a magnet in relation to the first and second magnetic sensors, and an analog signal processing module for providing an algebraic manipulation of the first waveform and the second waveform to generate a linear position output voltage signal.
