    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.

    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 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： Apparatus and method for IR-drop and supply noise measurements electronic circuits. A first voltage at a point of interest in the circuit is sampled and stored during a quiescent mode of the circuit the voltage is to be measured in. Subsequently, the circuit is brought in an operating mode and a second voltage is sampled and held at the same point of interest. The first and the second voltage are compared and a corresponding voltage signal is passed to a system output.
