Optical CMOS sensor for angular measurements with readout electronics
Costa, J. P. C.; Gounella, R. H.; Granado, T. C.; Machado, R. T.; Assagra, Y. A.O.; Correia, J. H.; Carmo, João Paulo PereiraThis paper presents an optical sensor for angular measurements to perform precise tracking of the sun's incident angle in a photovoltaic system. This microdevice was designed using a 0.18μm CMOS technology from TSMC. The microdevice is composed by a matrix of photodiodes and their respective readout electronics. A set of microstructures were used to resolve the angles of rotation by measuring the angle of incid...
