  • Publication number: 20090074106
    Abstract: Transmitters supporting multiple modulation modes and/or multiple frequency bands are described. A transmitter may perform large signal polar modulation, small signal polar modulation, and/or quadrature modulation, which may support different modulation schemes and systems. Circuit blocks may be shared by the different modulation modes to reduce cost and power. For example, a single modulator and a single power amplifier may be used for small signal polar modulation and quadrature modulation. The transmitter may apply pre-distortion to improve performance, to allow a power amplifier to support multiple frequency bands, to allow the power amplifier to operate at higher output power levels, etc. Envelope and phase distortions due to non-linearity of the power amplifier may be characterized for different input levels and different bands and stored at the transmitter.

  • Publication number: 20090016110
    Abstract: A method of reading data in a non-volatile memory device includes applying a bit line read voltage to a bit line and a selected cell read voltage to a word line, both of which are electrically connected to a selected cell located in a selected string. A first read voltage is applied to word lines electrically connected to first non-selected cells separated from the selected cell in the selected string, and a second read voltage is applied to word lines electrically connected to second non-selected cells adjacent to the selected cell in the selected string. The second read voltage is lower than the first read voltage. A pass voltage is applied to turn on a string select transistor and a ground select transistor, respectively, in the selected string. An electrical signal output from the selected string is compared with a standard signal to read data stored in the selected cell.
