Introduction Transistors are key to electronics. They are the building blocks of almost all devices. They switch, amplify, and regulate electrical signals. So, they are vital in modern electronics. Of the various types, bipolar junction transistors (BJTs) and field-effect transistors (FETs) are the most common in circuits. Importance of BJTs and FETs in circuit design

Introduction to Field-Effect Transistors (FETs) Field-Effect Transistors (FETs) are key in modern electronics. They control current flow in a semiconductor using an electric field. These transistors are widely used. They have high input impedance and low power usage. This makes them essential in many analog and digital circuits. Brief History and Development of FETs The

Introduction to Bipolar Junction Transistor (BJT) A semiconductor device with three terminals is called a bipolar junction transistor (BJT). It is vital in electronics. It acts as a current-controlled switch and amplifier. Unlike field-effect transistors (FETs), which are voltage-controlled, BJTs are bidirectional. They use both electrons and holes as charge carriers. It consists of two
