High Isolation, Low Power High Speed Multiplexer Circuit

View page
US Patent:
6636077, Oct 21, 2003
Filed:
Jun 11, 1999
Appl. No.:
09/330875
Inventors:
Charles E. Chang - Thousand Oaks CA
Andre Metzger - La Jolla CA
Assignee:
Conexant Systems, Inc. - Newport Beach CA
International Classification:
H03K 19082
US Classification:
326105, 327407
Abstract:
A high-isolation, low-power high-speed multiplexer circuit suitably includes a buffer stage and a current steering tree stage. By employing common select lines for both stages of the circuit, both the input buffer and the deselected channel provide cumulative isolation for the deselected channels.

Quiescent Current Control Circuit For Power Amplifiers

View page
US Patent:
7046087, May 16, 2006
Filed:
Aug 10, 2004
Appl. No.:
10/915279
Inventors:
Amish Naik - Los Angeles CA, US
Andre Metzger - La Jolla CA, US
Thomas L. Fowler - Moorpark CA, US
Assignee:
Skyworks Solutions, Inc. - Irvine CA
International Classification:
H03G 3/20
US Classification:
330136, 330296
Abstract:
According to one exemplary embodiment, a circuit arrangement includes a power amplifier configured to receive an RF input signal. The circuit arrangement further includes a control circuit configured to receive and convert the RF input signal to an output DC voltage. The control circuit includes a voltage amplifier coupled to a peak detector circuit, where the peak detector circuit outputs the output DC voltage. The circuit arrangement further includes an analog control bias circuit coupling the output DC voltage to a bias input of the power amplifier. The output DC voltage causes the power amplifier to have a quiescent current that increases in a way that is substantially logarithmic with respect to the amplitude of the RF input signal. An increase in the RF input power can cause a substantially linear increase in the output DC voltage, where the RF input power is measured in dBm.

Bias Control For Reducing Amplifier Power Consumption And Maintaining Linearity

View page
US Patent:
7262657, Aug 28, 2007
Filed:
Mar 21, 2005
Appl. No.:
11/085931
Inventors:
Keith Nellis - Sherman Oaks CA, US
Andre Metzger - La Jolla CA, US
Grant Small - Hiawatha IA, US
Michael L. Hageman - Ely IA, US
Terry J. Shie - Cedar Rapids IA, US
Kerry Burger - Chandler AZ, US
Assignee:
Skyworks Solutions, Inc. - Woburn MA
International Classification:
H03G 3/20
US Classification:
330133, 330136
Abstract:
A method and apparatus for biasing an amplifying device whereby the bias current tracks the input power or the power level of a control signal to thereby efficiently match the bias current with needs of the amplifying device. This method and apparatus overcomes the drawbacks of the prior art by biasing, not for maximum output power, but for the power level of the input signal or the control signal. In one embodiment a current conditioner operates in connection with the self adjusting biasing circuit to scale or adjust, potentially on an exponential basis, the biasing current for one or more amplifier stages. A cancellation current source may be configured within the bias circuit to cancel unneeded current to further minimize current consumption.

Continuous Tunable Lc Resonator Using A Fet As A Varactor

SKYWORKS SOLUTIONS, INC. - Woburn MA
International Classification:
G05F 3/02
H01L 21/8248
