摘要： An information handling system including a frequency synthesizer lock detection system is disclosed that distributes a frequency synthesizer output signal across a distribution network to one or more receptor circuits. The distribution network may exhibit delay and other distortion that may cause the downstream signal arriving at the receptor circuit to lose frequency lock with both the frequency synthesizer output signal and a reference clock signal that controls the frequency of the synthesizer output signal. The lock detection system tests the downstream signal to determine if the downstream signal exhibits a lock with respect to the reference clock that determines the operating frequency of the frequency synthesizer. In this manner, lock of the downstream signal to the reference clock signal may be accurately assessed in one embodiment.

摘要： An apparatus and method for extracting a maximum pulse width of a pulse width limiter are provided. The apparatus and method of the illustrative embodiments performs such extraction using a circuit that is configured to eliminate the majority of the delay cells utilized in the circuit arrangement described in commonly assigned and co-pending U.S. patent application Ser. No. 11/109,090 (hereafter referred to as the '090 application). The elimination of these delay cells is made possible in one illustrative embodiment by replacing an OR gate in the circuit configuration of the '090 application with an edge triggered re-settable latch. The replacement of the OR gate with the edge triggered re-settable latch reduces the amount of chip area used in addition to the power consumption of the circuit.

摘要： A method, an apparatus, and a computer program are provided for the semi-automatic extraction of an ideality factor of a diode. Traditionally, current/voltage curves for diodes, which provided a basis for extrapolating the ideality factors, had to be determined by hand. By employing a thermal voltage proportional to absolute temperature (PTAT) generator in conjunction with an extraction mechanism, the ideality factor can be extracted in an semi-automatic manner. Therefore, a reliable, quick, and less expensive device can be employed to improve measurements of ideality factors.

摘要： An apparatus and method for automatically calibrating a duty cycle circuit for maximum performance are provided. A chip level built-in circuit that automatically calibrates the duty cycle correction (DCC) circuit setting for each chip is provided. This chip level built-in circuit includes a clock generation macro unit, a simple duty cycle correction (DCC) circuit, an array slice and built-in self test unit, and a DCC circuit controller. Results of a built-in self test, i.e. pass or fail, of an array are provided to the DCC circuit controller. If the result of the built-in self test is a pass, then the current DCC circuit controller's DCC control bit setting is set as the setting for the chip. If the result from the built-in self test is a fail, the DCC circuit controller's DCC control bits setting is incremented to a next setting and the self-test is performed again.

摘要： The present invention provides for a method for characterization of pulse-width limiter outputs. A known clock signal is received. A pulse width of the received known clock signal is limited through a first pulse-width limiter to generate a first intermediate signal. The first intermediate signal is delayed by a known amount to generate a first delayed signal. The first intermediate signal is inverted to generate a first inverted signal. A pulse width of the first inverted signal is limited through a second pulse-width limiter to generate a second intermediate signal. The second intermediate signal is delayed by a known amount to generate a second delayed signal. A logic OR operation is performed on the first delayed signal and the second delayed signal to generate a clock out signal.

摘要： 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.

摘要： 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.

摘要： A system and system for automatic voltage calibration is presented. A voltage calibration system includes three main units, which are a voltage level trimming unit, a trim detection unit, and a trim control unit. The three units work in conjunction with each other during a trimming operation in order to identify a tap voltage that is closest to a target voltage. In one embodiment, the voltage calibration system may be used to calibrate a voltage regulator. Upon commencement of calibration, the voltage regulator's feedback loop is open, and the target voltage is selected as the input for the feedback port of the amplifier. The voltage regulator serves as a voltage comparator that compares each tap voltage to the target voltage. When the calibration is complete, regulator's feedback loop is closed and the closest tap voltage to the target voltage is used as the regulator's input.
