超寬頻低雜訊放大器與地震感測器系統設計

本論文為兩部份，第一部份為設計超寬頻低雜訊放大器(UWB LNA)。從過去到現在，低雜訊放大器為收發機模組中缺一不可的原件，它在接收端的位置上，主要是將發射端傳出的訊號，接收後將訊號放大，以減少傳遞訊號時的失真。為了能設計出節省面積且低雜訊與低功率放大器，此低雜訊放大器是採用變壓器來替代電路中的電感，以節省整個電路面積，在核心電路架構中是採用共源共閘疊接放大器，來提升此電路的頻寬，可有效的降低電晶體的操作電壓與電流，以達到低功率的目的。第二部份為地震感測系統設計。在現代，因全球人口快速的成長下，許多在地震帶下的城市，人口密集發展，只要有規模較大的地震發生下，重大災害迅速的擴散，造成不可抹滅的傷亡如近年日本的311大地震，造成了核電場的損壞，無數城鎮的建築損毀。為了能減少大地震造成的災害，我們將致力的研發地震感測系統，此系統是利用三軸加速度感測器來偵測地震的P波與S波，再經由類比數位轉換器(ADC)，將電壓訊號轉成數位資料的方式，在經由網路上傳至已架設好的即時監測伺服器上，對地震波數據進行分析與發佈警報，並與市面上現有的地震感測器做比較。

The manuscript is composed of two parts. The part one is design of ultra-wideband low noise amplifier (UWB LNA). From the past to the present. LNA original indispensable of transceiver module. It is at the receiving, mainly emanating from the transmitter signal, the receiver will reduce to the signals at passed times. To be able save thrift of the low power low noise amplification. It is used to the transformers replace to the inductance of the circuit, in order to thrift the area of circuit. It is used to the common-source amplifier cascode as gates to enhance the bandwidth of circuit architecture, which can achieve effectively reduce the operating voltage and current and low power consumption of transistors. The second part is the design of Earthquake Monitoring System, this system is the use of three-axis acceleration sensor to detect seismic P-wave and S-wave, and then through the analog to digital converter (ADC). The voltage signal converted into digital data of the way through Internet upload to the server has been set up of the host PC. It is using Windows 7 to set up our servers, design Borland C + + Builder (BCB) of the real-time monitoring systems. Has reached analysis of the P wave and S-wave seismic data, and available market to compare of the Earthquake Monitoring System.
