摘要： The invention relates to a magnetic field sensor comprising a substrate having a first side (S1). The substrate comprises at the first side (S1) a silicon comprising semiconductor layer (P-SUB) which comprises a buried N-well (DNW). A bipolar transistor having an emitter region (PE+, NE+), a base region (PB+, NB+), and a first collector region (CLR1) and a second collector region, is provided in the silicon comprising semiconductor layer (P-SUB). The emitter region (PE+, NE+) is located at the first side (S1) above the buried N-well (DNW). According to the invention the bipolar transistor is arranged such that, in operation, a part of an emitter current (IEM) that traverses the base region (PB+, NB+) is distributed over the first and second collector regions (CLR1, CLR2) obtaining a first and a second collector current (ICL1, ICL2), wherein a difference between the first and second collector currents (ICL1, ICL2) is determined by a magnetic field component (B x, B z ) perpendicular to a current plane. A bipolar magneto-transistor structure is obtained which is compatible with triple-well technology and that is sensitive to magnetic fields in a direction perpendicular to the current plane. The magnetic field sensor is compatible with triple-well technology and has a high linearity and a high sensitivity. The invention further relates to an integrated circuit comprising such magnetic field sensor (Snsr) and a card provided with such integrated circuit.

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 ofa 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： Apparatus and method for IR-drop and supply noise measurements in 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.
