场效应晶体管（Field Effect Transistor缩写(FET)）简称场效应管。由多数载流子参与导电，也称为单极型晶体管。它属于电压控制型半导体器件。具有输入电阻高（10^8～10^9Ω）、噪声小、功耗低、动态范围大、易于集成、没有二次击穿现象、安全工作区域宽等优点，现已成为双极型晶体管和功率晶体管的强大竞争者
各类场效应管根据其沟道所采用的半导体材料，可分为N型沟道和P型沟道两种。所谓沟道，就是电流通道。
半导体的场效应，是在半导体表面的垂直方向上加一电场时，电子和空穴在表面电场作用下发生运动，半导体表面载流子的重新分布，因而半导体表面的导电能力受到电场的作用而改变，即改变为加电压的大小和方向，可以控制半导体表面层中多数载流子的浓度和类型，或控制PN结空间电荷区的宽度，这种现象称半导体的场效应。
场效应管属于电压控制元件，这一点类似于电子管的三极管，但它的构造与工作原理和电子管是截然不同的，与双极型晶体管相比，场效应晶体管具有如下特点：
（1）输入阻抗高；
（2）输入功耗小；
（3）温度稳定性好；
（4）信号放大稳定性好，信号失真小；
（5）由于不存在杂乱运动的少子扩散引起的散粒噪声，所以噪声低。
根据构造和工艺的不同，场效应管分为结型和绝缘型两大类。

信息内容：材料多为硅或砷化镓单晶，并采用外延工艺技术。反偏电压愈大，则结电容愈小。变容二极管具有与衬底材料电阻率有关的串联电阻。对于不同用途，应选用不同C和Vr特性的变容二极管，如有专用于谐振电路调谐的电调变容二极管、适用于参放的参放变容二极管以及用于固体功率源中倍频、移相的功率阶跃变容二极管等。 用于自动频率控制（AFC）和调谐用的小功率二极管称变容二极管。通过施加反向电压， 使其PN结的静电容量发生变化。因此，被使用于自动频率控制、扫描振荡、调频和调谐等用途。通常，虽然是采用硅的扩散型二极管，但是也可采用合金扩散型、外延结合型、双重扩散型等特殊制作的二极管，因为这些二极管对于电压而言，其静电容量的变化率特别大。结电容随反向电压VR变化，取代可变电容，用作调谐回路、振荡电路、锁相环路，常用于电视机高频头的频道转换和调谐电路，多以硅材料制作。 变容二极管有玻璃外壳封装（玻封）、塑料封装（塑封）、金属外壳封装（金封）和无引线表面封装等多种封装形式、如图4-18所示。通常，中小功率的变容二极管采用玻封、塑封或表面封装，而功率较大的变容二极管多采用金封。 作用于调谐电路 如右图所示，改变不同的...
