  • Method for selecting capacitors
    Patent number: 6753800
    Abstract: A method for selecting capacitors in a charge redistribution digital-to-analog converter. m capacitors are arranged in the charge redistribution digital-to-analog converter. First, a signal is input to the charge redistribution digital-to-analog converter to identify n output units of the charge redistribution digital-to-analog converter. Then, the initial capacitor at the initial address and the following n−2 capacitors at the following n−2 addresses are continuously selected and if the following n−2 capacitors comprise the blank capacitor, the next capacitor is selected instead of the blank capacitor and a new blank capacitor is identified. Next, the initial address is changed to the address of the capacitor next to the last selected capacitor. Finally, the n−1 selected capacitors are output for the output units of the charge redistribution digital-to-analog converter. The n and m are positive integers and m>n>=1.

  • Dual-mode receiver and receiving method thereof
    Publication number: 20040058661
    Abstract: A receiving method for dual-mode receiver. When a received communication signal is a wideband signal, the dual-mode receiver is configured as a direct-conversion receiver, and when a received communication signal is a narrowband signal, the dual-mode receiver is configured as a low-IF receiver.
