Abstract
A high-temperature SIMOX technology using tungsten metallization has been employed for fabrication of a 1.7 mm2 low-offset temperature compensated Hall-readout IC. The chip is suitable for automotive applications up to 200 deg C. The automatic offset cancellation scheme allows for time continuous operation with 0.6mV offset.
