Patent JP-2011511605-A (JP)
IPC: H03F1/26
Filed: 2009-02-06
Abstract: A differential low noise amplifier (LNA) is operable in a selectable one of two modes. The LNA includes a first transistor, a second transistor, a third transistor and a fourth transistor. In the first mode (PDC mode), the four transistors are configured to operate as a post-distortion cancellation (PDC) LNA. The third and fourth transistors operate as cancel transistors that improve linearity, but reduce LNA gain somewhat. In the second mode (high gain mode), the third and fourth transistors are configured so that amplified versions of the LNA input signal that they output are added to amplified versions of the LNA input signal that are output by the first and second main transistors, resulting in increased gain. Multiplexing circuits are provided within the LNA so that the LNA is configurable into a selectable one of the two modes by controlling a digital mode control signal supplied to the LNA.

Title: Variable rate speech coding
Inventor: MANJUNATH SHARATH
IPC: G10L19/18
Filed: 2011-01-07
Abstract: <P>PROBLEM TO BE SOLVED: To attain a low bit rate in a method and apparatus for variable rate coding of a speech signal.  <P>SOLUTION: An input speech signal is classified and an appropriate coding mode is selected based on this classification. For each classification, the coding mode that achieves the lowest bit rate with an acceptable quality of speech reproduction is selected. Low average bit rates are achieved by only employing high fidelity modes during portions of the speech where this fidelity is required for acceptable output. Lower bit rate modes are used during portions of speech where these modes produce acceptable output. The input speech signal is classified into active and inactive regions. Various coding modes are applied to active speech, depending upon the required level of fidelity. Coding modes may be utilized according to the strengths and weaknesses of each particular mode. The apparatus dynamically switches between these modes as the properties of the speech signal vary with time.  <P>COPYRIGHT: (C)2011,JPO&INPIT
