| dc.description.abstract | 整流器是能量擷取系統中一個很重要的電路。本論文針對2.4-GHz整流器做了三個研究。第一個研究中，提出了傳統單端式整流器的最佳化方法，並以此方法設計出了兩顆整流器，其最佳能量轉換效率分別為51.43%以及18.13%。第二個研究中，提出一個能隨著輸入功率大小做自我調整的高效率整流器架構。這個架構使整流器的輸入功率範圍得以大幅增加，亦即無線操作的距離限制能夠大幅減小。根據文獻[6]，最佳轉換效率範園是指效率大於峰值的80%輸入能量範園，因此所設計的整流器最佳轉換效率範園有11dB，比其他文獻多了3dB以上。最後一個研究，則做出一個結合了高效率整流器以及電源管理電路的無線充電電路，能在充電後提供穩定1.8V、3mA電流給後級電路使用。 | zh_TW |
| dc.description.abstract | The rectifier is one of the most important circuits in power harvesting systems. In this thesis, three works about the 2.4-GHz rectifier have been done. In the first research, an optimization method of the conventional single-type rectifier is proposed. Through this optimization process, two rectifiers with the peak PCE equal to 51.43% and 18.13% are designed. In second work, a high-efficiency adaptive rectifier is proposed. By this structure, the input power range is expanded which means the limitation of the wireless operating distance can be relaxed a lot. According to [6], the optimal PCE region is the RF input power range where the PCE is larger than 80% of the peak PCE. Therefore, the optimal PCE region of the proposed rectifier is 11dB which is improved by over 3dB compared with other works. In final work, a wireless charging circuit which consists of a high efficiency rectifier and a power management circuit is proposed. This charging circuit can provide stable 1.8V voltage and 3mA current to back-end circuits. | en |
