摘要： A frequency sensing voltage regulator is disclosed. A source follower transistor has a gate connected to a predetermined gate voltage, a drain coupled to an external supply voltage through a switching transistor, and a source connected to a load. The gate of the switching transistor is controlled by a delay circuit through which a pulse derived from the system clock is passed. Through the use of the delay circuit and the switching transistor, the amount of current produced by the source follower transistor is made a function of the cycle rate of the system clock and the current provided by the source follower transistor tracks the frequency-dependent current requirements of the load, resulting in a reduced variance of the supply voltage Vcc over a wide current range.

摘要： A voltage-controlled delay element utilizes a current-starved inverter configuration with a feedback path that ensures a rapid discharge of the storage node to ground once the desired delay time has elapsed. The circuit comprises a circuit path for charging the storage node (preferably rapidly), a first pull-down path capable of discharging the storage node at a rate determined by the control voltage, a second pull-down path capable of rapidly discharging the storage node, an output inverter, and a feedback connection between the output terminal of the output inverter and the second pull-down path to rapidly discharge the storage node when the output voltage starts rising. The circuit further comprises a means for programmably adjusting the delay in response to logic signals.

摘要： A method and circuitry for controlling the rate of power dissipation of CMOS microcircuits during start-up. In accordance with the invention, either the clock frequency or the duty cycle of clock activity is changed, from zero at the instant of application of the power supply voltage, to the final operating frequency or activity at the end of a warm-up period. As a result, transient temperature differentials between integrated circuit die and the substrates to which they are attached are minimized, increasing the reliability of the CMOS circuitry.

摘要： A temperature and processing compensated time delay circuit of the type which can be fabricated in a monolithic integrated circuit utilizes a field effect transistor (FET) (12) connected to the terminals of a charged capacitor (14). A bias voltage connected to the gate of the FET (12) varies with temperature in a manner to compensate for the changes in current which flows from the capacitor (14) through the FET (12) due to changes in temperature. The bias voltage also varies from one integrated circuit to another in a manner to compensate for variations in FET threshold voltage caused by variations in the processing of the integrated circuits.

摘要： A constant propagation delay current reference is provided having an external source providing a reference frequency signal. A phase lock loop is provided which is responsive to the reference frequency signal and to an operating frequency signal to provide a current reference signal at the output of the loop. The current reference signal is provided to a current to frequency converter which generates the operating frequency signal. A current mirror, also coupled to the phase lock loop output provides an output current proportional to the current reference signal which is suitable for providing the injector current for I.sup.2 L devices. The output current tracks the process, voltage and temperature variations of the integrated circuit, allowing the injector currents to be optimized for maintaining constant propagation delay in the circuits being powered.

摘要： The semiconductor integrated circuit device incorporates a power supply circuit which forms an operation voltage that matches the operation speed of the internal circuit. Since the operation voltage is set in accordance with the operation speed required of the internal circuit, the internal circuit can be operated with a minimum required voltage even when there are process variations and temperature changes. In other words, a rational power supply is realized.

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