Which type of FET is known for its high input impedance?

Which type of FET is known for its high input impedance?

Step 1: Understand what a FET is. A FET (Field Effect Transistor) is a type of transistor that controls the flow of current using an electric field.
Step 2: Learn about different types of FETs. The main types are JFET (Junction FET) and MOSFET (Metal-Oxide-Semiconductor FET).
Step 3: Focus on input impedance. Input impedance is a measure of how much a device resists the flow of current at its input.
Step 4: Identify which FET has high input impedance. MOSFETs are known for having very high input impedance compared to other types of FETs.
Step 5: Conclude that MOSFETs are suitable for applications where high input impedance is important, such as in amplifiers and sensors.
