摘要： A wireless transceiver includes receiver front-end circuitry for processing an ingoing radio frequency (RF) signal to produce an in-going digital signal to a processor connected to receive the in-going digital signal. The processor includes sync word determination logic configured to identify a received sync word or other event or connection point and to subsequently generate an event determination signal. A low power oscillator produces low frequency pulses to a first counter. A crystal oscillator that produces higher frequency pulses to a second counter is used for the last portion of the desired sleep time for greater resolution. Thus, a calibration controller receives pulse counts from at least one of the first and second counters and determines a period between a common event of subsequent beacon signals or connection events and determines wake up times based on the received pulse counts from at least one of the first and second counters.

摘要： A numerically-controlled phase-lock loop with input clock dependent ratio adjustment provides for narrower-bandwidth loops that lock to a wide range of frequencies and/or operation with an absent or degraded input timing reference. A timing reference characteristic detector determines an input frequency range of the input timing reference signal, the data type of the timing reference, and/or whether a timing reference signal of sufficient quality is present. A numerically controlled oscillator is controlled by a numeric ratio that is adjusted to provide the desired clock frequency output in conformity with the detected frequency range and/or data type. If the timing reference signal is absent or degraded, then the numeric ratio can be set to a fixed value or a local timing reference can be applied in order to generate the desired clock output frequency.

摘要： A radio frequency identification device includes an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.

摘要： A data/clock recovery circuit can recover high-rate data using the data as a clock signal. It includes an edge detector, a clock selection signal generating circuit, a clock selection circuit and a synchronizing circuit. The edge detector generates edge position information using a receiver output as a clock signal. The clock selection signal generating circuit generates a clock selection signal in response to the edge position information using the receiver output as the clock signal. The clock selection circuit selects a recovered clock signal from a clock signal group in response to the clock selection signal. The synchronizing circuit synchronizes the receiver output using the recovered clock signal, and outputs it as a synchronized data signal.

摘要： A phase-locked loop (PLL), particularly useful for ADSL frequency locking applications, uses inexpensive external components in combination with versatile logic that can be implemented in a programmable logic device or an application specific integrated circuit. The PLL has the ability to revert to center-frequency operation in the absence of a timing reference and to adapt to a variety of reference frequencies through logic selection.

摘要： A method of forming an integrated circuit including a Schottky diode includes providing a substrate of a first conductivity type, defining a region of a second conductivity type relative to the substrate and forming an insulator over the second conductivity type region. The method also includes removing an area of the insulator for definition of a contact hole, and removing an area encircling the contact hole and forming highly doped regions of the second conductivity type in second conductivity type regions encircling the contact hole. The method further includes depositing a Schottky metal in the contact hole and annealing the metal to form a suicide interface to the second conductivity type region.
