Abstract: A solar greenhouse structure includes a plurality of supporting frames, a light-permitting roof supported by at least one supporting frame, and at least one solar panel disposed below the roof and near the bottom surface thereof. The instant disclosure uses thinner solar panels, where the supporting frames can be less rigid, in lowering the solar greenhouse cost.

Abstract: 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.
