场效应晶体管的概念场效应晶体管(以下简称场效应管——译者注),通常用 FET 表示。FET 是 FieldEffect Transistor 的缩写。所以称为场效应管在于它是一种由电场来控制电流的晶体管,与一般的利用注入基极的电流来进行控制的晶体管有着根本的区别。从这一点说,场效应管 Field Effect Transistor The concept of field effect transistor (FET), usually FET. FET is the abbreviation of FieldEffect Transistor. So called FET is that it is a kind of electric field to control the current transistor, and the general use of the current injected into the base to control the transistor has a fundamental difference. From this point, the FET
