摘要： Compensation coil functionality and flip coil functionality are combined into a single combination coil that is placed under an angle α with respect to the length direction of a magneto-resistive sensor element. The angle α substantially deviates from 0° and 90°. This configuration enables to reduce the width of the current line of the planar combination coil, to reduce the effective threshold for sensor element switching, and to include features to simplify a 2D sensor design.

摘要： An emitter-coupled transistor pair consisting of a first (T1) and a second (T2) transistor in which the a.c. component (+ib) in the base-current of the first transistor is compensated for by the a.c. component (-ib) of the second transistor. A replica of the later a.c. component (-ib) is available in the base-current of a third transistor (T3) which has its collector-emitter path connected in the collector line of the second transistor and which has its base coupled to the base of the first transistor.

摘要： A PAL-NTSC color television standard identification circuit, comprising a first demodulation circuit (7) for a reference component and a second demodulation circuit (11) for a possible color identification component of a color synchronizing signal, can perform a reliable identification by means of a digital decoding circuit (81) for the output signals of the demodulation circuits if the second demodulation circuit (11) is adapted (41, 45, 49) to demodulate along an axis slightly differing from the axis of the color identification component (FIG. 1).

摘要： An amplifier used in a tuner of video and/or audio equipment has to amplify the received input signal but should add as little as possible noise and distortion to the amplified signal. To improve the operation of the amplifier and includes tuner, the amplifier of the at least two gain stages and switches for short-circuiting a gain stage when it is not necessary for the overall gain value.

摘要： Self-adjusting frequency demodulation circuit comprising a frequency demodulator (13) which is designed as an integrated circuit, the adjustment being effected with the aid of a calibration signal source (7) of one single frequency and a measuring circuit (113, 35, 101) coupled to an output (113) of the frequency demodulator (13) by controlling the output signal amplitude of the frequency demodulation circuit with a multiplier (21) which is controllable by the measuring circuit and forms part of a tuning correction circuit which optionally may further include a level shifting circuit (57). The frequency demodulation circuit is particularly suitable for use in a SECAM color television receiver, only one frequency demodulator then being required for demodulating both the two color difference signals and the identification signal.

摘要： The method for inspecting an integrated circuit comprising a plurality of sub-circuits includes the determination of the supply current into at least one of the sub-circuits. This supply current is determined, while the other sub-circuits are operational, by measuring the voltage over a segment of the supply line through which this supply current flows. This supply line contains no additional components to facilitate the measuring of the voltage.

摘要： An extreme level circuit for determining an extreme level of a plurality of input levels includes a plurality of independent parallel branches (T4+M2+M5, T5+M3+M6) with intercoupled output terminals (MAX) from which the extreme level can be taken. Each branch has an input terminal (INA, INB) for receiving a respective one of the input levels, and includes a separate distortion compensation circuit (M2+M5, M3+M6) which is independent of the distortion compensation circuits of the other parallel branches.

摘要： In a multiphase output oscillator a number of serially coupled oscillator circuits is organized in a loop. Each particular oscillator circuit is coupled to its serial successor in the loop, to provide adjustment of the phase of an oscillation signal of the successor oscillator circuit dependent upon a difference between the phase of the oscillation signal in the successor and the phase of an oscillation signal in the particular oscillator circuit. None of the oscillator circuits will oscillate freely: as each oscillator will adjust its successor all the way around the loop. Indirectly, each oscillator circuit thus influences all of the other oscillator circuits and ultimately over itself. The multiphase output oscillator as a whole will oscillate in a collective mode of oscillation wherein all oscillator circuits oscillate at the same frequency. Successive oscillator circuits along the loop will oscillate at respective fractions of the full oscillation period delayed from each other. These fractions will add up to an integer multiple of periods. The frequency of oscillation is substantially independent of the fractions and may be nearly the maximum attainable frequency of the individual oscillator circuits.
