Monotonic Frequency Tuning Technique For Dcxo In Cellular Applications
US Patent:
7782152, Aug 24, 2010
Filed:
Sep 30, 2008
Appl. No.:
12/241103
Inventors:
Hooman Darabi - Irvine CA, US
Yuyu Chang - Irvine CA, US
Zhimin Zhou - Rancho Palos Verdes CA, US
Morteza Vadipour - Woodland Hills CA, US

Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H03B 5/32
US Classification:
331177V, 331158
Abstract:
A frequency tuning device for use in a crystal oscillator circuit includes a first fine tuning array of capacitors, a second fine tuning array of capacitors and a coarse tuning array of capacitors coupled in parallel to produce a tuning capacitance for tuning the crystal oscillator. The first fine tuning array of capacitors includes a binary weighted switched capacitor network, the second fine tuning array of capacitors includes a thermometer coded switched capacitor network and the coarse tuning array of capacitors includes a binary weighted switched capacitor network with a different unit capacitance value than the first and second fine tuning arrays.
Self-Testing Transceiver Architecture And Related Method
US Patent:
2012007, Mar 29, 2012
Filed:
Sep 24, 2010
Appl. No.:
12/924353
Inventors:
Masoud Kahrizi - Irvine CA, US

Assignee:
BROADCOM CORPORATION - Irvine CA
International Classification:
H04W 24/00
US Classification:
455 73
Abstract:
A self-testing transceiver comprises a receiver, and a transmitter including a power amplifier (PA) and a plurality of transmitter pre-PA stages. The plurality of transmitter pre-PA stages are configured to generate a communication signal at a receive frequency of the transceiver and the receiver is configured to process another communication signal at a transmit frequency of the transceiver, thereby enabling transceiver self-testing. A method for use by a transceiver for self-testing comprises generating a first communication signal at a transmit frequency of the transceiver by a transmitter of the transceiver, processing the first communication signal by a receiver of the transceiver, generating a second communication signal at a receive frequency of the transceiver by the transmitter, and processing the second communication signal by the receiver. The described generating and processing of the first and second communication signals resulting in self-testing by the transceiver.
