场效应晶体管与普通三极管的区别在于它的电流只包括一种载流子的运动,而普通三极管的电流包括二种载流子(电子和空穴)。前者称单极型晶体管,后者称双极型晶体管;前者为电压控制器件,后者为电流控制器件。由于场效应晶体管具有电子管的特点而与普通三极管又不同,但又具备了普通三极管的许多优点,这就使得场效应晶体管得到广泛地应用。目前应用的场效应晶体管可
The difference between a field effect transistor and a conventional transistor is that its current includes only one kind of carrier motion, whereas the current of a normal transistor includes two types of carriers (electrons and holes). The former refers to a unipolar transistor, which is called a bipolar transistor; the former is a voltage control device, the latter is a current control device. As the field-effect transistor with the characteristics of the tube and the ordinary transistor is different, but with many advantages of ordinary transistors, which makes the field-effect transistor is widely used. Currently used field-effect transistor can be
