Abstract

Position sensors are, in volume, the most prevalent sensor in cars. Fully integrated Hall CMOS sensors dominate the automotive position sensor market (magnetic sensor market on 7% CAGR, Online. https://www.eenewsanalog.com/news/magnetic-sensor-market-7-cagr. Accessed Dec 2017). They face challenging operating conditions including wide temperature range (−40 °C to +160 °C) and electromagnetic compatibility (EMC). Design techniques combining Hall elements (HEs), low- and high-voltage transistors are presented to address the sensor accuracy while meeting EMC performance with latest automotive standards. The sensor is implemented in a 0.18 um XFAB HV CMOS technology.
