摘要： Chip logic, a frequency multiplication and/or division, a temperature sensing circuit, and a power management circuit, are integrated on a very large scale integrated (VLSI) circuit chip. The temperature sensing circuit directly measures the chip temperature, producing a temperature output signal. The power management circuit, which is connected to the temperature sensing circuit and to the chip logic, responds to the temperature output signal and to a functional state of the chip logic to generate a control signal to the PLL. The PLL responds to the control signal to either stop the clock signal or modify the operating frequency of the clock signal, depending upon the state of the control signal.

摘要： An on chip delay regulator circuit which varies the power in logic or array circuits on the chip so as to minimize, or eliminate, chip to chip circuit speed differences caused by power supply variations and/or lot to lot process differences, temperature, etc. The on chip delay regulator accomplishes this by comparing a periodic reference signal to a periodic on chip generated signal which is sensitive to power supply changes, lot to lot process changes, temperature, etc. The comparison creates an error signal which is used to change the power (current or voltage) supplied to the on chip circuits. By changing the circuit power, the circuit speed (gate delay) is increased or decreased as necessary to maintain a relatively constant circuit speed on each chip. For example, a plurality of integrated circuit chips each contain an on chip delay regulator. The on chip delay regulator on each chip of said plurality of integrated circuit chips receives and responds to the same signal (or clock). Each chip provides a discrete on chip generated signal related to the parameters of the chip. The gate delay (or speed) of the circuitry on each chip is determined by its on chip delay regulator under control of the common reference signal (or clock). At least certain of the chips include an AC measurement circuit for comparing the periodicity of said reference signal with the periodicity of said on generated chip signal and cooperating with the delay regulator thereof to provide one of three discrete electrical manifestations.

摘要： Systems and methods for circuits with substantially equal propagation delay while providing different drive strengths are disclosed. These systems and methods may allow for a circuit with a drive strength that is some ratio of an arbitrary strength full drive strength circuit. Additionally, these circuits may have substantially the same input capacitance and feedback current as the baseline drive circuit. The input of such a circuit may be coupled to three nodes, one of which is an inverter coupled to the logic to be driven, the second of which is dummy logic, and the third of which is an inverter the output of which is left floating.

摘要： A memory clock generator apparatus and method are implemented. The memory clock is generated, “open loop,” from a processor clock. The processor clock is gated into, and propagated through a shift register. A set of outputs tapped off of the shift register is decoded, along with a plurality of control signals, in AND-OR logic to generate a clock output, which may run at a predetermined multiple of the memory clock rate. The clock output may have one of a plurality of ratios of memory clock period to processor clock period. The control signals select the ratio. The clock generator may be started asynchronously, and, additionally, the generator outputs a signal to the processor having an edge that has a predetermined temporal relationship with the start of the clock generator.

摘要： A driver circuit for a capacitively loaded line employs the charge storage capacitance of a diode for raising the base of a driver transistor above the circuit power supply voltage level 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 a driver transistor, the collector of which is connected to the power supply and the emitter of which is connected to the line. A switching transistor has an input voltage applied between its base and emitter. A diode is connected between the switching and driver transistors, the anode being connected to the base of the driver transistor, and the cathode being connected to the collector of the switching transistor.In response to a first input signal, the switching transistor turns on, forward biasing the diode 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 transistor turns off, raising the anode to the power supply voltage, and raising the cathode (and the base of the driver transistor connected thereto) to a voltage higher than the power supply voltage. The emitter of the driver transistor (and the line connected thereto) is thus pulled up to a value nominally approaching the power supply voltage, despite the base-emitter voltage drop of the driver transistor.
