    摘要: A flat-plate MIMO array antenna includes a substrate, a plurality of antenna elements disposed on the substrate, and at least one isolation element interposed between a plurality of antenna elements on the substrate and connected to a ground. Mutual interference between the antenna elements is prevented by the isolation element formed between the antenna elements, thereby preventing the distortion of the radiation pattern. Also, since the isolation element is grounded to the ground surface, the isolation element operates as a parasitic antenna, thereby increasing the output gain.

    摘要: A charge pump circuit includes a first switch for connecting an input terminal to a first pumping node, a first pumping capacitor for boosting up a voltage level of the first pumping node in response to a first control signal, a second switch for connecting the first pumping node to an output terminal, a third switch for connecting the input terminal to a second pumping node, a second pumping capacitor for boosting up a voltage level of the second pumping node in response to a second control signal, and a fourth switch for connecting the second pumping node to the output terminal. The charge pump circuit decreases a loss of an output voltage and prevents malfunctions in MOS devices by preventing damages of gate oxides of the MOS devices due to excessively high voltage differences.
