摘要： A band gap reference circuit in which a desired constant voltage is obtained without appreciably increasing the number of components. The base-to-emitter voltage of a transistor 22 is equal to the base-to-emitter voltage of a transistor 19, because the current of 2I flows through a parallel connection of two NPNs. If this voltage is Vbe1, the resistance of a resistor 28 is Re, the resistance of the resistors 29, 30 is 2R and the emitter voltage of the transistor 23 is VO′, this voltage VO′ is given by the following equation: Vo′=2 Vbe 1+2 (R/Re)·1n(n)·Vt such that a voltage twice the voltage Vo is outputted by summing the sum of the base-to-emitter voltages of two transistors to the thermal voltage multiplied by a coefficient proportionate to the number of transistors (two).

摘要： A geomagnetic direction sensor has a plurality of magnetic cores for converging terrestrial magnetism arranged circumferentially with pre-set gaps, and magneto-resistive effect devices in the gaps so as to lie substantially at right angles to the direction of the magnetic field in the gaps. The geomagnetic direction sensor has at least a pair of magneto-resistive effect devices lying substantially at right angles to each other. The magnetic core is formed of a magnetic material having soft magnetic properties. The current is supplied to the excitation coils placed around the magnetic core for applying a bias magnetic field to the magneto-resistive effect devices. Another set of magneto-resistive effect devices are connected in series with the magneto-resistive effect devices arranged within the gap so as to be substantially parallel to the direction of the magnetic field.

摘要： A recording/reproducing apparatus for a magneto-resistive (MR) head having a playback amplifier, including a capacitor for a dc feedback low-pass filter for do feedback to an initial-stage transistor, and a differential amplifier (gm amplifier), and a switching device for the gm amplifier and for the initial-stage amplifier operable at the time of recording/playback switching. The timing of the switching device is deviated for shortening the switching time interval. To this end, an output of the initial-stage transistor of a playback amplifier for a MR head is compared to reference voltage Vref by a gm amplifier and the low-pass filter is constituted by transconductance gm of the gm amplifier and the capacitance of the capacitor, with the dc output of the gm amplifier being fed back to the base of the initial-stage amplifier. The delay in switching time by the charging of the capacitor caused by the difference in the rise time of the initial-stage transistor and the gm amplifier is deviated by the control signal from a control circuit to control the initial-stage transistor and the gm amplifier.
