In the late 1990s I was working for a company that manufactures sub-systems for tramways, subways and light rail car manufacturers. One day my boss tells me that one of our inverters, a 5 kW DC to ...

Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in the selection of proper transistor type and calculation of voltage and current flowing through it. A ...

Here we propose, for the first time, a solar cell characterized by a semiconductor transistor structure (n/p/n or p/n/p) where the base–emitter junction is made of a high-bandgap semiconductor and the ...

The base leg acts as the control and needs around 0.6 volts (V) to switch ‘on’. Once an input of 0.6 volts has triggered the base leg, a much larger current can flow through the collector or emitter ...

Open-collector outputs are useful for transmitting buffered digital/pulse signals to the external world when high drive is needed. In harsh operating environments like automotive systems, however, ...

The chipmaker will shed light on a series of changes it's making to transistors that ideally will keep a lid on the growing problem of power consumption. Michael Kanellos is editor at large at CNET ...
