  • Patent number: 8278996
    Abstract: A reference current generating circuit includes an operational amplifier having one input terminal to receive a reference voltage and a field effect transistor having a gate to receive an output voltage of the operational amplifier. k resistors (k is an integer not less than 2) are connected in series to a drain of the field effect transistor, and a voltage at one of connection points of the resistors is feed backed to the other input terminal of the operational amplifier. A switch selects one of the connection points of the resistors and applies the voltage of the selected connection point as a reference voltage to a gate of a reference transistor to generate a reference current.

  • Patent number: 7917795
    Abstract: A method, an apparatus, and a computer program are provided to measure and/or correct duty cycles. Duty cycles of various signals, specifically clocking signals, are important. However, measurement of very high frequency signals, off-chip, and in a laboratory environment can be very difficult and present numerous problems. To combat problems associated with making off-chip measurements and adjustments of signal duty cycles, comparisons are made between input signals and divided input signals that allow for easy measurement and adjustment of on-chip signals, including clocking signals.

  • Patent number: 7724056
    Abstract: A semiconductor integrated circuit device includes a processor, a first clock generating section and a control section. The processor core operates in synchronism with a first clock and includes first and second critical paths. The first clock generating section controls a duty of an externally input second clock to generate the first clock. a control section detects a first phase difference between the first clock and a third clock obtained by delaying the first clock by a delay time in the first critical path and a second phase difference between the first clock and a fourth clock obtained by delaying the first clock by a delay time in the second critical path. The control section instructs the first clock generating section to control the duty so as to minimize a difference between the first and second phase differences.

  • Patent number: 7716516
    Abstract: A technology for supplying a power supply voltage to a microprocessor. Before normal arithmetic processing of the microprocessor, duty cycle correction process for adjusting the duty cycle of a clock signal inside the microprocessor is performed. In the duty cycle correction process for adjusting the duty cycle, the duty cycle of the clock signal is adjusted so as to minimize the power voltage at which the microprocessor is still operable.

  • Patent number: 7519498
    Abstract: The present invention provides a method, an apparatus, and a computer program product for measuring the temperature of a microprocessor through the use of ESD circuitry. The present invention uses diodes and an I/O pad within ESD circuits to determine the temperature at the location of the ESD circuitry. First, a current measuring device connects to a diode. A user or a computer program disables the protected component or circuitry, and subsequently applies a predetermined voltage to the I/O pad. This creates a reverse saturation current through the diode, which is measured by the current measuring device. From this current the user or a computer program determines the temperature of the microprocessor at the diode through the use of a graphical representation of diode reverse saturation current and corresponding temperature.
