The circuit acts like an efficient diode. With Enable low, the hot-swappable side has no effect on the signal, with or without power applied. The two-transistor circuit offers the additional benefit ...

This circuit is far from being only of academic interest in the audio field in that it can provide, for example, a very effective low input impedance amplifier circuit for a moving coil pick-up ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are go… ...

Field-effect transistors fabricated from carbon nanotubes have been investigated extensively over the past two decades. This study demonstrates a nanotube-based integrated circuit design that ...

This is precisely the frontier being explored through quantum thermal transistors, devices designed to replicate electronic transistor functionality at the quantum scale, but for heat.

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backwa… ...

Scientists have created a thermoelectric organic transistor. A temperature rise of a single degree is sufficient to cause a detectable current modulation in the transistor.

The world's fastest transistor has been developed by a pair of US researchers, possibly paving the way for a new generation of super-charged electronic chips. Milton Feng and Walid Hafez at the ...

"We are the first in the world to present a logic circuit, in this case a transistor, that is controlled by a heat signal instead of an electrical signal," states Professor Xavier Crispin of the ...
