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： Apparatus and associated methods may relate to Magneto-Resistive Sensing Devices (MRSDs). In accordance with an exemplary embodiment, an MRSD comprises an underlying semiconductor device and a magneto-resistive sensor. In some exemplary embodiments, the semiconductor device is processed through most of a standard process flow. After the standard process flow, in various embodiments, a planarization step may be performed to create a more planar top surface. In some embodiments, the magneto-resistive material, which may be made from a Nickel-Iron alloy, called Permalloy, is deposited on the planar surface. A layer of interconnect metallization also may reside in this top region. The magneto-resistive material may contact the topmost layer of metallization of the semiconductor device via contact openings in the planarized surface. In some embodiments, the magneto-resistive material may similarly contact the topmost layer of metallization through these contact openings. The magneto-resistive material resides directly above the underlying circuitry.

摘要： This disclosure is directed to techniques for decoding two or more signals that vary sinusoidally with respect to a parameter value to produce a decoded signal that varies linearly with respect to the parameter value. The techniques may include receiving a first signal and a second signal, the first signal varying with respect to a parameter value according to a first sinusoidal function having a period and a first phase, the second signal varying with respect to the parameter value according to a second sinusoidal function having the period and a second phase different from the first phase. The techniques may further include performing one or more arithmetic operations using the first signal, the second signal, and an offset value to generate a third signal that varies linearly with respect to the parameter value for at least one-half of the period of the first signal and the second signal.

摘要： Two bridge type transducers are coupled in series with their outputs each driving one of a pair of differential amplifiers, with the outputs tied together in a push-pull configuration. In further embodiments, push-pull operation is obtained by matching amplifier gain components and using current mirrors. Lower voltage operation may be achieved by simple diode level shifting of the transducer outputs. In one embodiment, the transducers comprise Hall effect sensors.
