How does a transistor work?3 answersA transistor is a device that controls the flow of electrical current. It consists of a transistor and a programmable controller. The controller has analog and digital computing circuitry that can be used to set up the analog circuitry. The transistor device has connectors to connect it to an external circuit, as well as a connector for programming the controller post-manufacture. The transistor itself has an active region, source and drain electrodes, and a gate. A spacer layer and field plate are provided to isolate the gate and the active region. The gate insulating layer of the transistor includes an impurity metal containing region that contacts the channel layer, as well as an impurity metal non-containing region that contacts the gate. The manufacturing process of a transistor involves forming semiconductor layers, etching cavities, and filling them with epitaxy. Another type of transistor includes a phase change layer that changes its physical property according to an applied voltage.
What are some applications of transistors as switches?3 answersStep 1:
Transistors are used as switches in various applications such as High Power Amplifiers (HPA) and solid-state microwave switches. They are also utilized in electrical power systems for protection during load faults and in RF switches for controlling the flow of current. Different types of transistors, including Metal Oxide Semiconductor Field Effect Transistors (MOSFET), Insulated Gate Bipolar Transistors (IGBT), and MOS Controlled Thyristors (MCT), are evaluated for their suitability in AC switch applications. Additionally, transistors with different threshold voltages, breakdown voltages, and on-resistances are employed in RF switches to provide specific characteristics without relying on different channel lengths.
