What is the main advantage of using a MOSFET over a BJT?
Step 1: Understand what a MOSFET is. A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of transistor that is controlled by voltage.
Step 2: Understand what a BJT is. A BJT (Bipolar Junction Transistor) is another type of transistor that is controlled by current.
Step 3: Compare how they are controlled. MOSFETs use voltage to turn on and off, while BJTs use current.
Step 4: Recognize the power consumption difference. Since MOSFETs are voltage-driven, they generally consume less power when they are in operation compared to BJTs, which require a continuous current to stay on.
Step 5: Conclude that the main advantage of using a MOSFET over a BJT is the lower power consumption due to its voltage-driven nature.
