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.
Claims6
A sensor, comprising:
- a magnetic position sensing element to generate angular position information;
- a first signal generator to generate a first waveform corresponding to the angular position information;
- a second signal generator to generate a second waveform corresponding to the angular position information, wherein the first and second waveforms are offset by a predetermined amount;
- 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.
