摘要： A sensor circuit is configured and operated in the presence of interference. In connection with various example embodiments, a stray magnetic field is sensed with current sensors that also respectively sense current-induced magnetic fields generated by current flowing in opposing directions through different portions of a conductor. The current-induced magnetic fields and the stray magnetic field are coplanar, and the current sensors are arranged such that a portion of the output from each current sensor corresponding to the stray magnetic field is canceled when the sensor outputs are combined.

摘要： A magnetoresistive angular sensor and sensing method, in which an external magnetic field generator is used to provide a first mode in which a dc external magnetic field is provided in a predetermined direction and which dominates over the magnetic field generated by the input device being sensed. In a second mode, the external magnetic field is smaller. The angular sensor arrangement outputs from the two modes are combined, and this enables the input device angular orientation to be determined with offset voltage compensation.

摘要： A current sensor, comprises an input conductor (IN) which is supplied with the current to be sensed and an output conductor (OUT) from which the current to be sensed is output. A conductor path is provided between the input conductor and the output conductor, wherein the path is provided on a first, movable element (1) and a second, fixed element (2). The path defines a pair of adjacent path portions (3,5; 3;4), one of the path portions (4;5) on the fixed element and the other (3) on one side of the movable element. An arrangement detects movement of the movable element to determine the current flowing. This arrangement uses a conductor path which can be part of the circuit being tested, and thereby does not require any additional components, other than the movement detector.

摘要： A sensor (400) for sensing jitter in a clock signal has a DLL (402, 310, 312) for locking a clock signal and a delayed version of the clock signal. The sensor comprises a delay line (402) having a first number of cascaded controllable delay segments. The DLL uses a second number of the cascaded delay segments for generating a delay of an average clock period of the clock signal. The second number is smaller than the first number. The sensor also has a comparator (408) for supplying a sensor output signal representative of a comparison of the clock signal and a further delayed version of the clock signal. The further delayed version of the clock signal is obtained from an output of a specific one of the delay segments located in the delay line after the second number of cascaded delay segments.
