使用並聯電容及電感設計反射式放大器

Abstract

本論文說明使用並聯電容及電感串接於電晶體源極設計反射式放大器，首先由基本理論說明振盪條件，分析閘極端之輸入阻抗，可由源極串接之共振回授電路，求得反射式放大器之操作頻寬，並提供設計回授電路元件值之流程，供設計者參考。

This thesis presents the design of reflection-type amplifier using shunt inductor and capacitor at the transistor source termination. The basic theory of oscillation condition is discussed in Chapter 1. In Chapter 2, analysis of the input impedance at the gate termination of a transistor with drain termination shorted and source terminated with a shunt LC resonator gives the operational bandwidth of a reflection amplifier. Furthermore, the design flow of choosing element values of the shunt inductor and capacitor is provided in Chapter 3, based on the required operational bandwidth as a reference for the circuit designer.
