A linearizing interface circuit with phase-error compensated direct-digital output for TMR-based angular position sensor

Abstract

This paper proposes a simple and efficient electronic interface circuit for Tunneling Magneto-Resistance (TMR) based angular position sensor. The proposed circuit takes-in and processes the sine and cosine natured outputs of a TMR angle sensor using a novel methodology, and provides a linear output with angle for a full-circle range. The new methodology… (More)
