  • Cam and crank sensor with current limiting open collector output for conducted emissions improvement
    Patent number: 7603892
    Abstract: A sensor apparatus and method include a sensor configured on an integrated circuit, which includes a current limiting open collector output stage configured in association with the integrated circuit. The current limiting open collector output stage reduces a fall time and a di/dt associated with an output signal of the sensor and a ringing produced thereof in order to improve EMC and conducted emissions required of the sensor.
    Type: Grant
