We will explore their unique characteristics, understand why they are considered strong, and discover their diverse applications in modern technology.
Semiconductors: The Foundation of Modern Electronics
Semiconductors are materials with an electrical conductivity that falls between that of conductors and insulators. This unique property allows them to control the flow of electricity under certain conditions, making them essential for various electronic devices.
What are PMOS Transistors?
PMOS transistors, also known as P-channel metal-oxide-semiconductor transistors, are a type of field-effect transistors (FETs) that utilize a P-type semiconductor material as the primary current-carrying channel. In a PMOS transistor, positive charge carriers, called holes, are responsible for conducting electricity.
