商品描述
Radio Frequency IDentification (RFID) stores and retrieves data using devices called RFID tags: objects attached to or incorporated into a product, animal or person which communicate with an RFID reader or interrogator. This book proposes a linear two-port model for an N-stage modified-Greinacher full wave rectifier, predicting the overall conversion efficiency at low power levels where the diodes are operating near their threshold voltage. Included is an experimental procedure to measure how impedance modulation in the tag affects the signal at the reader, and a useful tool for choosing the most appropriate impedances.
商品描述(中文翻譯)
無線頻率識別（RFID）使用稱為RFID標籤的裝置來儲存和檢索數據：這些標籤附著在產品、動物或人身上，並與RFID讀取器或詢問器進行通信。本書提出了一個N階改良型Greinacher全波整流器的線性雙端口模型，預測在二極體接近其閾值電壓的低功率水平下的整體轉換效率。書中還包括一個實驗程序，用於測量標籤中的阻抗調變如何影響讀取器的信號，以及一個選擇最合適阻抗的有用工具。
