摘要： A voltage regulator operable as a voltage follower while a fusible link is closed and in a regulated voltage mode when the fusible link becomes open. The voltage regulator can be formed on monolithic semiconductor chips. Patterned thin films including aluminum and nickel-iron, and aluminum and polycrystalline silicon, comprise the fusible link. With the fusible link closed, the voltage regulator output is an analog of positive polarity variable voltage levels at the regulator input. Systems powered by the voltage regulator are allowed to be programmed until system programming requiring variable voltage levels is complete. Afterwards, a negative polarity voltage is applied to the regulator input causing a large current to pass through the fusible link once the system programming is completed. Current thereby causes the fusible link to become opened and enables the voltage regulator to begin operating at a regulated voltage in response to positive voltage input.

摘要： A first magnetic sensor is formed on a semiconductor substrate, and the first magnetic sensor produces a first output signal in response to movement of a multi-pole magnet. A second magnetic sensor is formed on the semiconductor substrate so as to be intertwined with the first magnetic sensor and so as to be at a predetermined angle with respect to the first magnetic sensor. The second magnetic sensor produces a second output signal in response to movement of the multi-pole magnet. The predetermined angle is between 0° and 180° exclusive, and the predetermined angle is sufficient to produce a difference in phase between the first and second output signals. An output signal converter converts the first and second output signals to a linear signal.

摘要： 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.

摘要： A magnetic sensing apparatus includes a first magnetic transducer separated spatially from a second magnetic transducer and proximate to a target and a direction decoding circuit associated with the first and second magnetic transducers, wherein the direction decoding circuit produces output pulses that provide data indicative of a rotation of the target while rejecting rotational vibration signals associated with the target during a rotational detection of the target utilizing the first and second magnetic transducers without producing erroneous output pulses or missing an excessive number of the output pulses during speed and rotational detection operations thereof.
