摘要： A voltage supply circuit which, by controlling a source voltage so that it is increased more greatly than it is decreased, can provide a stabilized operating source voltage adapted to cope with a sudden change in load and allows a semiconductor integrated circuit to realize low power consumption while maintaining normal operation. A replica circuit (20) is provided and the delay time in the critical pass of a LSI (10) is detected to compare the delay time detected by a control circuit (50) with a predetermined reference value, control being effected such that if this comparison shows that the delay time is greater than the reference value, the supply voltage VDD to the LSI (10) is raised, whereas if it shows that the delay time is smaller than the reference value, the supply voltage VDD to the LSI (10) is lowered; controlling a supply voltage so that the amount of raising of the supply voltage is greater than the amount of lowering of the supply voltage makes it possible to quickly restore the supply voltage VDD to the reference value or above if it lowers to the reference value or less. The time in which malfunction of the LSI (10) may occur can be greatly reduced and besides this, the operating stability of the voltage supply circuit can be improved.

摘要： A voltage supply circuit capable of dealing with an abrupt change of a load by controlling an amount of increase of a power source voltage to be larger than an amount of reduction, supplying a stable operating power source voltage, and realizing lower power consumption while maintaining normal operation of a semiconductor integrated circuit is provided. By providing a replica circuit (20), detecting a delay time of a critical path of an LSI (10), comparing a delay time detected by a control circuit (50) with a predetermined reference value, performing control to raise a voltage (VDD) supplied to the LSI (10) when the delay time is larger than the reference value as a result of the comparison and to lower the voltage (VDD) supplied to the LSI (10) when the delay time is smaller than the reference value, and making the amount of increase at the time of raising the supplied voltage larger than the amount of reduction at the time of lowering it, when the supplied voltage (VDD) becomes smaller than the reference value, it can be quickly restored to be larger than the reference value, the time when operating error of the LSI (10) may occur can be greatly shortened, and the operational stability of the voltage supply circuit can be improved.

摘要： Bei dieser Schaltung, die als Regelschaltung auf jedem Halbleiterchip vorgesehen ist und eine Phasenvergleichsschaltung enthält, in der die Frequenz eines den Sollwert der Signalverzögerung charakterisierenden, extern zugeführten Impulszuges mit der Frequenz eines auf dem Halbleiterchips befindlichen steuerbaren Oszillators verglichen wird, ist eine Zusatzschaltung vorgesehen. Sie ist an die Phasenvergleichsschaltung angeschlossen und besitzt drei Ausgänge, um anzuzeigen, ob die Frequenz des steuerbaren Oszillators kleiner, gleich oder größer als die des extern zugeführten lmpulszuges ist. Die Zusatzschaltung ist aus drei Verknüpfungsgliedern aufgebaut.

摘要： A digital timing signal generator and voltage regulator circuit is provided. In one embodiment the circuit includes a delay line. The delay line operating voltage is derived from digitally encoded power/timing signals transmitted by an isolated logic control circuit. The delay line receives and propagates the digitally encoded signals. Outputs of selected stages of the delay line are tapped to provide multiphasic timing signals for use by associated logic circuits. A plurality of gates having inputs connected to various stages of the delay line receive selected timing signals as they propagate along the delay line. Increases in the operating voltage cause the selected timing signals to sequentially activate the gates. The output of each activated gate then goes high and current flows through an associated load resistor connected between the output of the gate and ground to continuously load the supply voltage and thereby regulate it. In variations of this embodiment, two and three levels of gates and load resistors are provided to progressively load the supply voltage and thereby provide additional regulation thereof. In another embodiment, a ring-oscillator comprised of CMOS inverters generates the timing signals. The ring oscillator consumes current in approximately a square relationship with increases in its supply voltage and thereby regulates the voltage.

摘要： An integrated circuit chip (l2) carries a number of electronic circuits (l4), at least one of which includes, in its output stage, a control device (l6) that responds to a reference signal (VREF) to adjust the output current-handling capability of the electronic circuit (l4), thereby regulating the signal propagation delay exhibited by the electronic circuit. The reference signal (VREF) is generated by a digital-to-analog circuit (l8) that is also formed on the chip (l2). The digital-to-analog circuit (l8) is coupled to a number of contact elements (l,2,3) disposed on an outer surface of the package (8) containing the integrated circuit chip that can be selectively interconnected to a DC voltage to choose the value of the reference signal.

摘要： A signal generating circuit for an integrated circuit device responsive to first (CS) and second (DATA IN) externally applied input signals occurring at a predetermined time interval In which the performance of a first input signal responsive circuit (12) is made to vary inversely with respect to the performance of other internal signal generating circuits (10,18, TC) such that internally generated signals will occur at a predetermined time with respect to the external input signals regardless of the influence of variable parameters. Power dissipation of the first input signal responsive circuit also varies inversely with respect to that of other circuits present on the integrated circuit device so that total power dissipation is minimized.
