Pixels are autonomous entities that can harvest or sense illumination independently. Pixels have a fully asynchronous operation and do not require to be scanned to read out their asynchronous output. The sensor was manufactured in UMC 180-nm technology and tested. Their specifications are competitive against the art, offering fast operation, a good balance between the energy consumed and harvested, and high-dynamic range operation. The article describes the sensor and pixel architectures in detail and provides experimental results. Sensor specifications are benchmarked against the art. © 2001-2012 IEEE.application/pdf12 p.engAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/Asynchronous operationDiode efficiencyEnergy harvestingImage sensorIntegrated photovoltaic cellsSelf-poweredStacked diodesTime-to-first-spike (TFS)info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/JSEN.2023.3248177
