Circuit Device And Method Of Coupling To An Antenna

US Patent:
2010032, Dec 23, 2010
Filed:
Jun 23, 2009
Appl. No.:
12/489825
Inventors:
Peter Onody - Budapest, HU
Attila Zolomy - Budapest, HU
Eric Unruh - San Jose CA, US
Assignee:
Silicon Laboratories, Inc. - Austin TX
International Classification:
H01P 5/12, H03H 7/38
US Classification:
333124
Abstract:
In an embodiment, a circuit device for coupling to an antenna includes a first impedance matching circuit configured to couple to the antenna and a second impedance matching circuit configured to couple to the antenna. The circuit device further includes a power amplifier coupled to the first impedance matching circuit and includes a low-noise amplifier coupled to the second impedance matching circuit. Additionally, the circuit device includes a selectable impedance adjustment circuit coupled between the low-noise amplifier and the second impedance matching circuit, which selectable impedance adjustment circuit is configured to selectively adjust an impedance associated with the low-noise amplifier when the power amplifier is transmitting a signal through the antenna.

Methods And Apparatus For Alteration Of Terminal Counts Of Phase-Locked Loops

US Patent:
2002016, Nov 14, 2002
Filed:
May 14, 2001
Appl. No.:
09/855423
Inventors:
Eric Unruh - San Jose CA, US
Scott Gibbons - San Jose CA, US
International Classification:
H03K023/50, H03L007/183, H03L007/195
US Classification:
331/00100A, 331/025000, 327/117000, 377/052000, 377/107000, 377/119000
Abstract:
A phase-locked loop (PLL) includes a down counter having a detection circuit configured to determine when the counter reaches its terminal count. The down counter also includes a control line configured to alter the terminal count detected by the detection circuit by an off-set.

Balanced Band-Pass Filter For Radio Receivers

US Patent:
7521991, Apr 21, 2009
Filed:
Nov 14, 2005
Appl. No.:
11/273517
Inventors:
Ilan Saul Barak - Kfar Saba, IL
Kobi Ben-Atar - Holon, IL
Eric L Unruh - San Jose CA, US
Assignee:
SPG Ltd. - Herzliya
International Classification:
H04B 1/10
US Classification:
327557, 327552
Abstract:
A filter includes an input and an output. First and second filter stages having respective stage inputs and stage outputs are connected in cascade between the input and the output. Each filter stage includes an amplifier having an amplifier input and an amplifier output and an inner feedback loop connecting the amplifier output to the amplifier input. An outer feedback loop connects the stage output of the second filter stage with the stage input of the first filter stage. The first and second filter stages and the outer feedback loop are arranged so that an s-space closed-loop transfer function of the filter includes two zeros and a single pole.
