| Title: | 55-pW/pixel Peak Power Imager with Near-Sensor Novelty/Edge Detection and DC-DC Converter-Less MPPT for Purely-Harvested Sensor Nodes | Authors: | Karim Ali Abdeltawwab Ahmed HAYATE OKUHARA Massimo Bruno Alioto |
Issue Date: | 21-Feb-2023 | Citation: | Karim Ali Abdeltawwab Ahmed, HAYATE OKUHARA, Massimo Bruno Alioto (2023-02-21). 55-pW/pixel Peak Power Imager with Near-Sensor Novelty/Edge Detection and DC-DC Converter-Less MPPT for Purely-Harvested Sensor Nodes. ScholarBank@NUS Repository. | Abstract: | A μW-range low-cost imager with on-chip detection of Regions of Interest (ROI) with novel content and power adaptation to purely-harvested sources is proposed. Novel content detection is achieved via inexpensive edge detection and edge point counting. Frame rate adaptation to light is enabled by a DC-DC converter-less MPPT loop for reduced system complexity. 55-pW/pixel always-on power is achieved in a 180-nm testchip powered by a 3.3x3.3-mm2 solar cell down to 100 lux. | URI: | https://scholarbank.nus.edu.sg/handle/10635/237223 |
