Abstract:
An exemplary embodiment of the present invention described and shown in the specification and drawings is a transceiver with a receiver, a transmitter, a local oscillator (LO) generator, a controller, and a self-testing unit. All of these components can be packaged for integration into a single IC including components such as filters and inductors. The controller for adaptive programming and calibration of the receiver, transmitter and LO generator. The self-testing unit generates is used to determine the gain, frequency characteristics, selectivity, noise floor, and distortion behavior of the receiver, transmitter and LO generator. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or the meaning of the claims.

Method And Apparatus For Fractional-N Synthesis
US Patent:
7231196, Jun 12, 2007
Filed:
Dec 12, 2001
Appl. No.:
10/015993

Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04B 7/00, H04B 1/18
US Classification:
455260, 4551651
Abstract:
A method and apparatus for fractional-N synthesis includes processing that begins by generating a 1feedback frequency from the output frequency based on a fixed divider value. The processing continues by generating a 2feedback frequency from the output frequency based on a selectable divider value, a modified fractional value of the divider value, and a modified integer value of the divider value. The processing continues by determining whether the fractional value of the divider value is within a range of fractional values. If so, the 1feedback frequency is used to produce the output. If the fractional portion of the divider value is not within the range of fractional values, the 2feedback frequency is used to produce the output frequency.
