    摘要: A driver circuit for a capacitively loaded line (24) employs the charge storage capacitance of a diode (21) for raising the base of a driver transistor (20) above the circuit power supply voltage level (V cc ) so as to pull up the line to within a transistor base-emitter voltage drop of the power supply voltage level. The driver is easily fabricated in integrated circuit form, as no capacitors, either on or off chip, are required. The driver circuit includes the driver transistor (20), the collector of which is connected to the power supply (V cc ) and the emitter of which is connected to the line (24). A switching transistor (22) has an input voltage applied between its base and emitter. The diode (21) is connected between the switching and driver transistors (22, 20), the anode being connected to the base of the driver transistor (20), and the anode being connected to the collector of the switching transistor (22). In response to a first input signal, the switching transistor (22) turns on, forward biasing the diode (21) and building up a voltage thereon as a result of the diode's charge storage capacitance. In response to a second input signal, the switching transitor (22) turns off, raising the anode to the power supply voltage (V cc ), and raising the cathode (and the base of the driver transistor (20) connected thereto) to a voltage higher than the power supply voltage. The emitter of the driver transistor (20) (and the line (24) connected thereto) is thus pulled up to a volume nominally approaching the power supply voltage (V cc ), despite the base-emitter voltage drop of the driver transistor (20).

    摘要: Zum Angleichen der unterschiedlichen Signalverzögerungszeiten der Logik-Gatter verschiedener Halbleiterchips ist auf jedem Halbleiterchip eine Regelschaltung (4) für die Signalverzögerung vorgesehen. Ihr wird als Bezugssignal ein externer, allen Halbleiterchips gemeinsamer Taktimpuls zugeführt. Die Regelschaltung vergleicht dessen Phasenlage mit der eines Impulszuges, der von einem zur Regelschaltung gehörenden spannungsgesteuerten Oszillator geliefert wird. Die als Vergleichsergebnis erhaltene und verstärkte Spannung beeinflußt den spannungsgesteuerten Oszillator, bis die beiden Impulszüge synchronisiert sind. Die verstärkte Spannung wird auch den Logik-Gattern zugeführt. Sie verändert deren Aufnahme von elektrischer Leistung so, daß die gewünschte Signalverzögerung, die eine Funktion der elektrischen Leistung ist, erreicht wird.

    摘要: For reducing self-induced switching noise a two terminal non-linear impedance means is connected to the collector of an output transistor (T1) of a driver circuit and the reference potential line. It comprises one or more serially connected diodes, which may be formed by the base-collector junctions of bipolar transistors (TS1, TS2).
