共基极

图1. 基本的 NPN 共基极电路 (忽略偏置细节)。
图例2: 计算不同参数的小信号模型; 作为电压信号来源的Thévenin.
图例 3: 附有牛顿驱动器的共基极电路; RC 会被省略因为一个主动负载被假设拥有无限小的信号输出电阻。

在电子学里，共基极放大器是三个基本单级BJT放大器结构的其中一种，通常被使用于电流缓冲或电压放大器。在这个电路中，射极作为输入端，集极作为输出端，基极为共用端（它可能接地，或是接到电源）。类似在场效应管电路的共闸极（common gate）。

Common base 共基极

Figure 1: Basic NPN common base circuit (neglecting biasing details).
Figure 2: Small-signal model for calculating various parameters; Thévenin voltage source as signal.
Figure 3: Common base circuit with Norton driver; RC is omitted because an active load is assumed with infinite small-signal output resistance

In electronics, a common base (also known as grounded-base) amplifier is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies, typically used as a current buffer or voltage amplifier.

In this circuit the emitter terminal of the transistor serves as the input, the collector the output, and the base is connected to ground, or "common", hence its name. The analogous field-effect transistor circuit is the common gate amplifier.
