Las ventajas del transistor de efecto de campo son evidentes. Al ser un dispositivo controlado por voltaje, puede controlar la corriente de paso mediante el voltaje de puerta. Además, la razón por la que la corriente de entrada es extremadamente baja es porque la resistencia de entrada es muy alta, pudiendo superar los 1,000 ohmios. Gracias a su conductividad, se observa que la temperatura es muy estable y no genera grandes cantidades de calor. Asimismo, el factor de amplificación de voltaje de este circuito amplificador es muy bueno. Posee una gran capacidad antiinterferencias frente a este tipo de radiación y puede utilizarse en numerosos circuitos.
There are two types of field effect transistors, namely junction field effect transistors and insulation. According to the conductive mode, the three field effect transistors can be seen as enhancement type and depletion type. Therefore, the combined field effect transistor is also a depletion type. In the face of such long effect transistors, it can be seen that this classification is still very simple, and its role in the amplification circuit is still very obvious. Therefore, in this type of circuit, the reason for the high input impedance is that capacitors are basically not used. If you look closely, you will find that all coupling capacitors are used, and electrolytic capacitors are basically not used. It can be used as a constant current source or an electronic switch. The overall function is still very powerful. The use of an electronic component like this can play a big role in a switching circuit. As a voltage control component, it can be seen that it is a unipolar device, and its flexibility is much better than that of a triode, so it is widely used in many integrated circuits.
