    Abstract: A high voltage generating circuit is disclosed. In the high voltage generating circuit a boost node is precharged and boosted by a plurality of pump circuits and then discharged to an output terminal. Where a voltage apparent at the boost node is smaller than a power supply voltage, the voltage apparent at the boost node is elevated to the power supply voltage. Where the voltage apparent at the boost node is larger than the power supply voltage, a current path is prevented from forming between the boost node and the power supply voltage so as to maintain the voltage apparent at the boost node.

  • Publication number: 20080022345
    Abstract: A demodulator, for example, a digital video broadcasting-handheld (DVB-H) demodulator may include an erasure table for storing erasure information, a multi-protocol encapsulation forward error correction (MPE-FEC) decoder configured to decode MPE-FEC data within an MPE-FEC frame based on the erasure information, and an erasure table controller configured to generate the erasure information based on a cyclic redundancy check (CRC) operation result regarding transport stream (TS) data to store the generated erasure information into the erasure table and output, to the MPE-FEC decoder, the stored erasure information corresponding to the MPE-FEC data when the MPE-FEC decoder decodes the MPE-FEC data. Therefore, the DVB-H demodulator may process the erasure information faster, for example, independently of a main processor, using the erasure table controller and/or the erasure table.
