Abstract
Quadrature signals are often found in angular position sensors such as linear scales and 2-axis Hall sensors. The phase of quadrature signals always carries the moving direction and position of a working platform. To increase the phase resolution, this paper presents a novel phase chopping method to convert the phase information into pulse sequences. With the help of an 8-bit analog-to-digital conversion upon each π/4 phase interval, the full 2π phase cycle can be digitized into 1,600 quasi-equipollent pulse resemblances and the phase error is bound within near one splitting phase division.
