摘要: | 人口老化已經成為現今社會中一大不可避免的問題,而提供給老人們適當的服務也愈顯重要。家庭用的醫療配備像是生理資訊無線接收紀錄器與居家環境偵測系統等將在可視之未來中扮演重要地位。因此,我們提出了超再生式接收機,可應用於無線上的訊號傳輸。為了分析誤碼率,我們也提出一個偵測電路整合於系統中。在最後,我們分析了超再生式接收機的操作原理,並建立了一個相關模型去嘗試解釋我們的測試成果。
整體電路均實作於聯華電子的0.18 微米製程,超再生式接收機用以解調開關鍵控訊號,其操作於 1 GHz 與1.8伏特的操作電壓。偵測電路主要由一高速計數器所構成,用以計算啟動時間的時間長度。我們藉由 TSPC (true single-phase clocked) 架構來實現數位電路。偵測電路也跟超再生式接收機一樣,操作於 1 GHz 與1.8伏特的操作電壓。 最後,我們探討超再生式接收機的操作原理,進一步建立了統計上的模型,來模擬壓控振盪器的暫態表現。藉此,我們可以得到超再生式接收機的最佳訊號偵測點,以達到最低的誤碼率。 Population aging has become an inevitable issue recently, making provide proper services for the elderly an urgent need. Homecare services like wireless recording for personal physiological information and home-based environmental monitoring system will become more and more important in the visual future. Therefore a super-regenerative receiver for biomedical applications is purposed. For bit error rate analysis, a detecting circuit is also integrated. In the end, we analyze the fundamental principle of a super-regenerative receiver and create a model to fit the result. Our circuit is implemented and fabricated in UMC standard 0.18um CMOS process. The super-regenerative receiver is to demodulate on-off keying signals. It operates at 1G Hz and 1.8 Volt of supply voltage. The detecting circuit mainly comprise a high speed counter, used to calculate the span of the start-up time. We use true single-phase clocked logic as our circuit structure. It also operates at 1G Hz and 1.8 Volt of supply voltage. In the last part, we focus on basic principle of super-regenerative receiver. Furthermore to create a statistical model, fitting transient behavior of a voltage controlled oscillator. Thereby, we can derive the optimal signal detection point of the super-regenerative receiver, and achieve minimum bit error rate. |
