A CMOS rotary encoder system based on magnetic pattern analysis with a resolution of 10b per rotation

A single-chip CMOS magnetic rotary encoder system based on magnetic pattern analysis is presented. Magnetic sensor arrays are integrated with ADCs and DSP circuits and fabricated in a standard 0.25 /spl mu/m CMOS technology. The chip detects the rotation angle within an error of /spl plusmn/0.36 deg...

Description
Summary:A single-chip CMOS magnetic rotary encoder system based on magnetic pattern analysis is presented. Magnetic sensor arrays are integrated with ADCs and DSP circuits and fabricated in a standard 0.25 /spl mu/m CMOS technology. The chip detects the rotation angle within an error of /spl plusmn/0.36 degrees (10b per rotation).
