    Abstract: A charge-pump circuit for charge-share suppression. A first switching element is coupled between a first connecting node and an output terminal. A first load receives a current from a first current source and outputs an output voltage at the output terminal when the first switching element is in “On” state. A status of a second switching element is controlled by the input signal and opposite to the status of the first switching elements A second current source is coupled to the second switching element through a second connecting node. A second load receives the output voltage when the second switching element is in “On” state. A first feedback circuit maintains a constant relation between the output voltage and a voltage of the first node. A second feedback circuit maintains a constant relation between the output voltage and a voltage of the second node.

    Abstract: A manufacturing method of a non-volatile memory is disclosed. A gate structure is formed on a substrate and includes a gate dielectric layer and a gate conductive layer. The gate dielectric layer is partly removed, thereby a symmetrical opening is formed among the gate conductive layer, the substrate and the gate dielectric layer, and a cavity is formed on end sides of the gate dielectric layer. A first oxide layer is formed on a sidewall and bottom of the gate conductive layer, and a second oxide layer is formed on a surface of the substrate. A nitride material layer is formed covering the gate structure, the first and second oxide layer and the substrate and filling the opening. An etching process is performed to partly remove the nitride material layer, thereby a nitride layer is formed on a sidewall of the gate conductive layer and extending into the opening.

    Abstract: The present invention relates to a debugging apparatus for a computer system and a method thereof. A detecting unit detects if a debugging unit connects to the computer system. When a debugging unit connects to the computer system, the detecting unit produces a detecting signal, which contains information of a bus in the computer system electrically connected with the debugging unit. Then a selection unit selects the bus electrically connected with the debugging unit according to the detecting signal. Besides, a testing unit tests the computer system and produces a power-on self-test (POST) code, so that the selected bus can be used for outputting the POST code to the debugging unit. Thereby, the present invention can choose to use the bus reserved in the computer system for outputting the POST code to the debugging unit, and hence facilitating inspection personnel to debug the computer system.

    Abstract: A communication device adopted for a multi-input multi-output orthogonal frequency division multiplexing (MIMO-OFDM) system and a method thereof are provided. The MIMO-OFDM system comprises the communication device and a corresponding communication device, and they communicate with each other. The communication device comprises a transceiving module, a singular value decomposition (SVD) operation module, and an interpolation operation module. The transceiving module receives a channel state information (CSI) from the corresponding communication device, wherein the CSI comprises CSIs of a plurality of selected subcarriers. For each of the selected subcarriers, the SVD module performs an SVD decomposition operation on the channel matrix representing the CSI of the selected subcarrier to obtain a decomposed result, wherein the decomposed result comprises a beamforming matrix, an SVD matrix, and a decoding matrix. The interpolation operation module performs interpolations on the beamforming matrices of the selected subcarriers to derive beamforming matrices of the unselected subcarriers. The interpolation operation module performs interpolations on the decoding matrixes of the selected subcarriers to derive obtain decoding matrices of the unselected subcarriers.
