A novel non-resonant electrostatic energy harvester is presented, which utilizes charges stored in the charge-trapping nonvolatile memory to replace external voltage source or electret for biasing the variable capacitor. The proposed harvester is fully compatible with the IC process and easy to be integrated with other electronic devices. Moreover, based on the modeling and simulation results, the...
A DC-DC converter with an embedded digital controller is implemented in 40 nm CMOS. The converter including the ADC, decimator, digital filter, and DPWM occupies 0.7 mm2 of which the area occupied by the output drivers is 0.6 mm2. It achieves >90% efficiency at 200 mA load.
In this paper, we propose to segment color images by pixel clustering in a selected color space. This color space is selected among a set of classical color spaces according to a specific criterion based on a spectral clustering analysis. The clusters are determined by analyzing the 3D-histogram of the image coded in the selected color space thanks to a spectral clustering method. This scheme can...
