    ICsense designed an ASIC to measure the speed and direction of rotating shafts in cars, engines, … . The ASIC was co-integrated with a GMR (giant magnetoresistant) sensor on a single die. The sensor measures the subtle differences in an applied static magnetic field. The readout ASIC for the GMR sensor includes digital processing. To enable a seamless co-simulation of the system, our engineers modeled the GMR sensor in VHDL-AMS.  The ASIC can operate in peak conditions of up to 200°C and was manufactured in a 0.65um BiCMOS process qualified for automotive environments.

    Features:

    • GMR (giant magnetoresistant) sensor readout ASIC

    • Ultralow power, Vdd is 2.5V
    • 12-bit accuracy
    • VHDL-AMS model of the sensor
    • 0.65um BiCMOS technology
    • Temperature range -40°C to 200°C
