1,Field-effect transistors (FETs) have the advantages of high input impedance and low noise, making them widely used in various electronic devices. Especially when used as the input stage in an electronic device, FETs offer performance that is difficult to achieve with standard transistors.

2,FETs are divided into two types: junction type and insulated-gate type, but the control principle for both is the same.

1. FETs are voltage-controlled devices, whereas transistors are current-controlled devices. In situations where the signal source can only provide a small current, an FET should be used. However, when the signal voltage is low and current needs to be drawn from the signal source, a transistor should be selected.
4. FETs can operate under very low current and low voltage conditions, and their manufacturing process allows for the integration of many FETs on a single silicon chip. This makes them widely used in large-scale integrated circuits.
