摘要： A phase-locked loop includes a variable frequency generator, a comparator and a counter. The variable frequency generator is configurable for generating an output signal having a frequency which varies based at least in part on at least first and second control signals presented thereto. The comparator is configurable for receiving a first signal and a second signal, the first signal being an input signal presented to the phase-locked loop and the second signal being representative of the output signal from the variable frequency generator. The comparator generates a difference signal representative of a difference between a phase and/or a frequency of the first and second signals, the difference signal comprising the first control signal. The counter is configurable for generating an output count based at least in part on the difference signal from the comparator. The output count is a digital representation of the difference signal, the output count comprising the second control signal. The frequency of the output signal from the variable frequency generator is determined as a function of the difference signal and the output count.

摘要： A baseband clock synthesizer having particular use in a BLUETOOTH piconet device, having the capability of generating either 12 MHz or 13 MHz clock signals generated from any reference clock signal, e.g., 12.00, 12.80, 13.00, 15.36, 16.80, 19.20, 19.44, 19.68, 19.80, and 26.00 MHz. A fractional-N frequency divider is implemented with a PLL including a variable divider allowing the use of virtually any reference frequency input to generate a locked 156 MHz clock signal used as a basis for a 12 MHz or 13 MHz baseband clock signal. A residue feedback sigma-delta modulator provides a varying integer sequence to an integer divider in a feedback path of the PLL, effectively allowing division by non-integer numbers in the PLL. Thus, the PLL can be referenced to virtually any reference clock and still provide a fixed output clock signal (e.g., 12 or 13 MHz).

摘要： A system and method for determining the classification of a signal, or the identification of an object is provided. Based on rough set theory, or data mining, a training data set is partitioned and labeled with a multi-class entropy method. Reducts are calculated from a subset of the best-performing columns of the partitioned and labeled training set data. These reducts are applied to test signals and combined for each signal classification. The present system and method produces a more accurate, robust and efficient classification result.

摘要： This disclosure relates to a cell-placeable variable-frequency digitally controlled oscillator (DCO) that consumes approximately the same current in a fast process corner as in the case of a slow process corner. By modulating the effective channel length of transistors in inverters, a fast process DCO may be slowed down to a desired frequency at nearly the same current consumption as that of a slow process DCO.

摘要： A ring oscillator including a voltage-to-current converter for producing at least one control current from at least one control voltage and, a plurality of delay cells coupled to the converter, wherein at least one output of the one of the delay cells is coupled to the input of another of the delay cells, wherein the voltage-to-current converter produces a substantially linear output when the at least one control voltage is varied between zero volts and a rail supply voltage. Since the ring oscillator operates from a low voltage source, it can be used in applications where power supply (e.g., battery size) is small (e.g., pagers, cellular phone applications).

The guiding catheter is comprised of a shaft section which is attached to an articulating section at its distal end and a first handle at its proximal end. The inner catheter is comprised of an elongated central shaft, an electrode assembly attached to the distal end of the central shaft, and a second handle attached to the proximal end of the central shaft. The electrode assembly is comprised of a flexible plastic catheter tube having an outer surface, a porous tip electrode, and at least one linear electrode carried on the outer surface of the catheter tube. The electrode assembly is articulated to better align the electrode assembly to the generally arcuate shape of the inner chambers of the heart.
