For the standard junction diode, there are two operating regions and three possible biasing conditions. There is no external potential energy applied to the P-N junction when a diode is connected in a ...

An N-channel JFET has a low bias current when its gate is biased negative to the source. However, this requires either that the gate voltage be biased negative with respect to the source voltage or ...

The X9530 laser-diode-bias controller incorporates all circuitry necessary to control the bias of a laser diode while allowing for compensation of temperature drift and laser-diode manufacturing ...

PIN diodes are named for a region of undoped intrinsic semiconductor lying between their p and n-type material. This area eliminates capacitance effects between the n and p-type areas that can ...

Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage. These types of diodes often are used for ...
