Research demonstrates improved efficiency in CIS control circuits by addressing power consumption and trade-offs.
CMOS image sensor (CIS) control circuit has a non-negligible problem, which is the power efficiency. Research has shown that the power consumption of the CIS control circuit is affected mainly during the process of converting light to voltage signals. By reviewing the related research and products that use CIS control circuits, this study aims to find the current efficiency and flaws of the components in CIS control circuits to provide an optimized solution for each impediment. We separate different components in CIS control circuits and analyze each of them with corresponding efficiency and obstacles to increase efficiency. Subsequently, ideas and solutions for overcoming the challenges to increase the efficiency of components with certain trade-offs will be provided. Based on the analysis of each possible solution, the team recommended future development for these solutions that may optimize the efficiency of CMOS image sensors with minimal trade-offs.
