傳統應用採用運算放大器（OPA）和R、C等離散元件實現積分器特性，但由於運算放大器元件的操作頻率受限，往往僅能於較低速的應用。
本論文中，我們提出一個以離散時域技術及電晶體的離散時域模型設計具增益的微波積分器的新方法，並利用此方法實現兩個不同正規化頻率的積分器。
此方法是利用離散時域的技術方法，將其電晶體之散射參數以Z多項式表示，再利用傳輸線鏈散矩陣和積分器系統轉移函數方程式作為系統程式的合成演算，找出微帶線的系統特徵阻抗並以串接多條單位電氣長度傳輸線於電晶體來實現具增益微波積分器，並以實驗結果來驗證此設計。

The integrator is an instrument tool evaluating the time integral of measured signals and a serial R-C circuit, in conjunction with an operational amplifier, has been frequently applied to the design of integrators.
So far, the integrators are primarily employed in circuit for low-speed applications. In the thesis, we propose a new method to implement the active integrators for high-frequency applications. The new method is applied to achieve the two kinds of integrators. In accordance with the practice of different normalized frequency, the integrators are eventually designed and fabricated.
In this method, the transfer function of integrator in z domain is described at first. Based on the transfer function, the z domain chain-scattering matrices of transmission lines and the better equation are then derived to realize the essential characteristic impedance in the thesis. Experimental results are presented to illustrate the validity of this method.
