Questions & Step-by-Step Solutions
What is the input impedance characteristic of a FET?
Step 1: Understand what input impedance means. It is the resistance that an input signal sees when it enters a device.
Step 2: Learn about FETs (Field Effect Transistors). They are a type of transistor used to control electrical signals.
Step 3: Know that FETs have a very high input impedance. This means they do not draw much current from the signal source.
Step 4: Recognize that high input impedance is beneficial in applications where you want to avoid loading down the signal source.
Step 5: Conclude that because of their high input impedance, FETs are ideal for use in circuits that require high sensitivity and minimal signal distortion.
