  • Publication number: 20150188419
    Abstract: A charge pump includes a chip and a package substrate packaged on the chip and installed in a circuit board. One of the 1st˜(X?Y)th external pins of the package substrate is electrically connected to the (X?Y)th input pin of the chip, and the other end of the same external pin is electrically connected to the input voltage of the circuit board. Thus, when the input voltage is being boosted through each capacitor of the circuit board, it is free from the action of the 1st through (X?Y?1)th transistors of the chip and therefore the original design of the 1st through (X?Y?1)th transistors can be maintained without causing any change in the output voltage Thus, the invention eliminates the problem of the prior art design that needs to change the internal circuit design when a different output voltage is required.

  • Publication number: 20150173093
    Abstract: Systems and methodologies are described that facilitate dynamically allocating demodulation resources of a wideband receiver to provide improved demodulation of simultaneously received signals. Signal-to-noise ratio (SNR) and/or packet error rate (PER) can be measured for the plurality of carriers to determine which demodulators related to the carriers require more resources than others to demodulate signals at a specified signal quality. Where the SNR of a related carrier is high and/or PER is low, the demodulator can require fewer resources than where the SNR of a related carrier is low and/or PER is high. In this regard, the resources are dynamically allocated among the demodulators and reallocated where SNR/PER changes and/or additional resources are made available.
