This allows construction of advanced light-emitting diodes and diode lasers. The basic components of analog circuits are wires, resistors, capacitors, inductors, diodes, and transistors. Transparent conductive polymers are used as electrodes on light emitting diodes and photovoltaic devices. Some common electronic components are capacitors, inductors, resistors, diodes, transistors, etc. Digital integrated circuits (ICs) consist of billions of transistors, resistors, diodes, and capacitors. A NAND gate is made using transistors and junction diodes. This new inverter can avoid extra clamping diodes or voltage balancing capacitors. They exclude devices like transistors, vacuum tubes, relays, tunnel diodes, and glow tubes. Gallium nitride on sapphire is commonly used in blue light-emitting diodes (LEDs). Commonly used for rectifier, Schottky, and other diodes. The compound semiconductors InGaN and InGaP are used in light-emitting diodes (LEDs) and laser diodes. One common design solution is to protect bussed signal pins with series diodes or resistors. Optical or photonic computing uses photons produced by lasers or diodes for computation. Light-emitting diodes (LEDs) can also used. Other uses in electronics include phosphors in fluorescent lamps and solid-state light-emitting diodes (LEDs).
