Transistors

Transistors are fundamental semiconductor devices in modern electronics, renowned for their dual capabilities as amplifiers and switches. As a three-terminal device, a transistor controls the flow of current between two terminals based on the input at the third. This property enables amplification of weak signals, high-speed switching, and the regulation of electrical output, forming the backbone of countless electronic devices. Transistors come in various types, including bipolar junction transistors (BJTs) for small-signal amplification, field-effect transistors (FETs) for high input impedance applications, and power transistors for handling larger currents. Each type brings unique benefits to different circuit designs.
