Brief Patent Description - Full Patent Description - Patent Application Claims
This application makes reference to, claims priority to, and claims the benefit of U.S. Provisional Application Ser. No. 60/895,698, filed on Mar. 19, 2007, which is incorporated herein by reference in its entirety. [Not Applicable] [Not Applicable] Certain embodiments of the invention relate to signal amplification. More specifically, certain embodiments of the invention relate to a method and system for gain control and power saving in broadband feedback low-noise amplifiers. As mobile, wireless, and/or handheld portable devices increasingly become multifunctional, “all-in-one,” communication devices, these handheld portable devices integrate an increasingly wide range of functions for handling a plurality of wireless communication services. For example, a single handheld portable device may enable Bluetooth communication, cellular communication and/or wireless local area network (WLAN) communications. Much of the front end processing for wireless communications services is performed in analog circuitry. Front end processing within a portable device may comprise a range of operations that involve the reception of radio frequency (RF) signals, typically received via an antenna that is communicatively coupled to the portable device. Receiver tasks performed on a received RF signal may include demodulation, filtering, and analog to digital conversion (ADC), for example. Noise considerations may be important since the strength of the received RF signal may be low. The resulting front-end processed signal may be referred to as a baseband signal. The baseband signal typically contains digital data, which may be subsequently processed in digital circuitry within the portable device. Front end processing within a portable device may also include transmission of RF signals. Transmitter tasks performed on a baseband signal may include digital to analog conversion (DAC), filtering, modulation, and power amplification (PA), for example. The power amplified RF signal is typically transmitted via an antenna that is communicatively coupled to the portable device by some means. The antenna utilized for receiving an RF signal at a portable device may or may not be the same antenna that is utilized for transmitting an RF signal from the portable device. One limitation in the inexorable march toward increasing integration of wireless communications services in a single portable device is that the analog RF circuitry for each separate wireless communication service may be implemented in a separate integrated circuit (IC) device (or chip). The increasing chip count may limit the extent to which the physical dimensions of the portable device may be miniaturized. Thus, the increasing integration may result in physically bulky devices, which may be less appealing to consumer preferences. The chip count may be further increased due to the need to replicate ancillary circuitry associated with each RF IC. For example, each RF IC may require separate low noise amplifier (LNA) circuitry, separate PA circuitry, and separate crystal oscillator (XO) circuitry for generation of clocking and timing signals within each RF IC. Similar replication may occur for digital IC devices utilized for processing of baseband signals from each separate wireless communication service. Along with an increasing IC component count, there may also be a corresponding rise in power consumption within the portable device. This may be undesirable due, for example, to increased operating temperature, and reduced battery life between recharges. Further limitations and disadvantages of conventional and traditional approaches will become apparent to one of skill in the art, through comparison of such systems with the present invention as set forth in the remainder of the present application with reference to the drawings. A system and/or method for gain control and power saving in broadband feedback low-noise amplifiers, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims. Various advantages, aspects and novel features of the present invention, as well as details of an illustrated embodiment thereof, will be more fully understood from the following description and drawings.
