It is becoming more important to evaluate the installed PV system's performance and loss factors to enhance the system's efficiency and pull more electric power from the systems. This paper describes the evaluation method of PV systems and summarizes the results of annual performance and loss analysis. Grid voltage and snow coverage are two major serious(More)
1,000 fps motion vector (MV) estimation and classification engine for highspeed computational imaging in a 3D stacked imager/processor module is proposed, prototyped, assembled, and also tested. The module features 1) ThruChip interfaces for high fps image transfer, 2) orders of magnitude more area/power efficient MV estimation architecture compared to(More)
Abstract This paper proposes 3D stacked module consisting of image sensor and digital logic dies connected through inductive coupling channels. Evaluation of a prototype module revealed radiation noise from the inductive coils to the image sensor is less than 0.4-LSB range along with ADC code, i.e., negligible. Aiming at high frame rate image(More)
