Analysis of Electret-Based MEMS Vibrational Energy Harvester With Slit-and-Slider Structure
Autor: Norio Sato, Kei Kuwabara, Mamoru Ugajin, Yasuhiro Sato, Kazuyoshi Ono, Toshishige Shimamura
Publikováno v: Journal of Microelectromechanical Systems. 21:1218-1228
This paper describes an analysis and a performance limit of a vibrational energy harvester with a novel slit-and-slider structure. This structure has a separable electret and microelectromechanical systems (MEMS) parts. In the MEMS parts, movable ele

Third-Harmonic Envelope Feedback Method for High-Efficiency Linear Power Amplifiers
Autor: Mamoru Ugajin, Shoichi Oshima, Mitsuru Harada
Publikováno v: IEICE Transactions on Electronics. :713-716
A new low-power feedback structure for a power amplifier (PA) reduces signal distortion while keeping the power efficiency of the PA high. The feedback structure injects the envelope of the third-order harmonics into the input signal. In adopting thi
