Filed:

Oct 18, 2000

Appl. No.:

09/692421

Inventors:

Shervin Moloudi - Los Angeles CA
Maryam Rofougaran - Marina Del Rey CA

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03F 345

US Classification:

330301, 330311

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.

Filed:

Apr 8, 2003

Appl. No.:

10/409213

Inventors:

Shervin Moloudi - Los Angeles CA

Assignee:

Broadcom Corp. - Irvine CA

International Classification:

H03L 700

US Classification:

331 16, 331 11, 332128

Abstract:

A phase locked loop includes a difference detector, a loop filter, a controlled oscillation module, and a frequency translation module. The difference detector is operably coupled to determine a difference signal based on phase and/or frequency differences between a feedback oscillation and a reference oscillation. The loop filter is operably coupled to generate a control signal from the difference signal. The controlled oscillation module is operably coupled to produce, in accordance with an adjustable operating parameter, an output oscillation based on the controlled signal. The adjustable operating parameter is set based on desired operating conditions of the phase locked loop such that false locking of the phase locked loop is substantially avoided. The frequency translation module is operably coupled to produce the feedback oscillation from the output oscillation based on a frequency translation rate.
