Abstract:
A sensor includes a magnetic position sensing element to generate angular position information, a first signal generator, a second signal generator, a first inverter to invert the first waveform for providing a first inverted waveform and a second inverter to invert the second waveform for providing a second inverted waveform, wherein the first and second waveforms are inverted about an offset voltage, and an analog signal processing module to generate a linear output signal from the first waveform, the second waveform, the first inverted waveform, and the second inverted waveform.
