Publication number: 20060030277Abstract: A fully integrated, programmable mixed-signal transceiver comprising a radio frequency integrated circuit (RFIC) which is frequency and protocol agnostic with digital inputs and outputs, the transceiver being programmable and configurable for multiple radio frequency bands and standards and being capable of connecting to many networks and service providers. The RFIC does not use spiral inductors and instead includes transmission line inductors allowing for improved scalability. Components of the transceiver are programmable to allow the transceiver to switch between different frequency bands of operating. Frequency switching can be accomplished though the content of digital registers coupled to the components.Type: ApplicationFiled: August 11, 2005Publication date: February 9, 2006Inventors: Russell Cyr, Geoffrey Dawe, Jose Bohorquez

Patent number: 6483871Abstract: A digital signal phase detector comprising a first circuit arranged to provide a phase difference signal representative of both the clock period of a clock signal and the difference in phase between the clock and a data signal, and a second circuit arranged to provide a reference signal representative of the clock period of the clock signal. At least one of the first and second circuits is coupled to a set point control signal and the corresponding output signal is representative of that set point control signal. A comparison of the phase difference signal with the reference signal provides an indication of the difference between the desired set point of the circuit and the phase difference between the clock and the data signal. A corresponding method of digital signal phase detection is also provided.Type: GrantFiled: December 28, 1998Date of Patent: November 19, 2002Assignee: Nortel Networks LimitedInventor: Piers James Geoffrey Dawe

Patent number: 6028898Abstract: The invention seeks to provide an improved, bandwidth-efficient method and apparatus for acquiring and tracking bursts of data, or continuous data, of varying and unpredictable amplitude, extinction ratio, and phase.The system avoids the use of digital signal processing which is not practical at high data signal rates. The system also obviates encoding of the data signal using a line code, thereby extending the existing technology to give a significant increase in data throughput for the same available bandwidth.The system may treat acquisition of each data burst, comprising alternate synchronisation parts and data parts, ab initio.Type: GrantFiled: April 24, 1997Date of Patent: February 22, 2000Assignee: Nortel Networks CorporationInventors: Adrian Paul Sparks, Piers James Geoffrey Dawe, Robert William Spagnoletti

Patent number: 5875188Abstract: An electrical switch (116) is disclosed having multiple inputs (214) and binary switches (312) operable to switch a signal from an input (214) via respective amplifiers (310). Amplifiers (310) are continuously operable and are provided with an auxiliary switching circuit (412) which provides the amplifier with a fixed voltage input signal when the associated input (214) is not selected. Response time upon selection of an amplifier (310) and crosstalk from any non-selected amplifier is minimised.Type: GrantFiled: April 18, 1996Date of Patent: February 23, 1999Assignee: Northern Telecom LimitedInventor: Piers James Geoffrey Dawe
