以混沌理論為基礎之類比除頻器設計
Design of Analog Frequency Divider Using Chaos Theory
摘要
此論文將混沌理論作為除頻器設計之基礎，利用新型NDR負微分電路的非線性特性來實現一種新型的除頻器架構，此架構只需要一顆電感、一顆電容、以及一個NDR電路組成，是一種架構簡單的電路。 我們可以藉由控制輸入頻率、電壓等等來得到不同的除頻因子(dividing ratio)與區間的混沌現象。 由於本篇論文有三種NDR架構，從模擬所得到的數值經過分析研究後發現除頻器操作準位電壓設定極為重要，必將其準位設置在負電阻區域的範圍內，否則會影響除頻器的除頻範圍與除頻因素大小。 經由適當設計後，此除頻器將具有高除頻因素。此除頻器電路的最大優點在於我們可用標準BiCMOS製程來設計與實現。

This paper will have Chaos Theory be the basic of Frequency Divider. Use the identities of Nonlinear of New-Type Negative Differential Resistance (NDR) to accomplish the skeleton of New-Type Frequency Divider. This skeleton only needs an inductor, a capacitor and a NDR circuit. It’s a simple circuit. We could obtain different dividing ratios and the period of output signal by controlling the frequency and offset voltage of the input signal. Owing to this paper sets three different types of NDR. We found that the setting of Frequency Divider is important after analyzing the data of Simulation. We must set the offset voltage in Negative resistance region, or that will affect the results of Frequency Divider and dividing ratios. As the result of proper design, this Frequency Divider will be provided with high dividing ratios. The strong point of this Frequency Divider circuit is that we could design and accomplish it with normal BiCMOS process.
