This application note discusses the switching capabilities of bipolar transistors, including charge analysis and circuit techniques to permit high-frequency saturated switching. Circuit examples are ...
In previous parts of this series we reviewed the basic transistor parameters that determine ac voltage gain and practical considerations limiting high gain. The role of a coupling capacitor was ...
Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...
Researchers have realized a f<sub>T</sub>/f<sub>MAX</sub> 245GHz/450GHz SiGe:C heterojunction bipolar transistor (HBT) device, a key enabler for future high-volume ...
Power control is provided by high-power devices and their drive circuits. A variety of power devices are used, including bipolar and MOSFET transistors, insulated-gate bipolar transistors (IGBTs), and ...
How many remote controls do you have in your home? Don’t you wish all these things were better integrated somehow, or that you could add remote control functionality to a random device? It’s a common ...
A pair of physicists in the US has built the fastest ever transistor: one that can operate at a frequency of over 600 gigahertz. Developed by Walid Hafez and Milton Feng at the University of Illinois ...
A transistor fabricated from the crystalline phase of an organic semiconductor material could provide a path to improved switching speeds — rivalling those of devices built from inorganic materials ...
