Patent number: 7978110Abstract: A system for converting a digital signal to an analog signal is provided. The present invention provides a digital-to-analog converter (DAC) that can convert a large bit value digital signal to a corresponding analog signal. The digital-to-analog converter includes a bias regeneration circuit, and three sub-DACs. The bias regeneration circuit provides biasing to the three sub-DACs allowing the DAC to be implemented with smaller circuit area. In addition, the three sub-DACs may be digitally calibrated during the conversion process to increase the linearity of the DAC.Type: GrantFiled: February 18, 2010Date of Patent: July 12, 2011Assignee: Taiwan Semiconductor Manufacturing Company, Ltd.Inventors: Yu-Jen Lai, Mei-Chen Chuang, Wen-Shen Chou

Publication number: 20110005128Abstract: A solar energy greenhouse includes a main structure, a roof structure disposed on the main structure and a plurality of thin-film solar cell assemblies which are disposed on the roof structure in an unequal gap defined there between. The thin-film solar cell assemblies can absorb sunlight and generate electrical energy. The unequal gaps between the thin-film solar cell assemblies are determined from the radiation angle of the sunlight and the position of plants in the solar energy greenhouse, so the amount that the sunlight radiates on the thin-film solar cell assemblies and the plants can achieve a better distribution, which improves the amount of electrical energy generated by the thin-film solar cell assemblies and the rates of growth of the plants.Type: ApplicationFiled: September 25, 2009Publication date: January 13, 2011Applicant: LITE-ON GREEN TECHNOLOGIES, INC.Inventors: Mei-Chen CHUANG, Cheng Chung, Ming-Chao Hsiao
