The air compressor is essential to the proper operation of subway cars that use an air brake system [1 ... This is a standard current limiter circuit [2] [3]. The transistor that failed the most was ...

On the one hand, using a high-value ... a transistor and resistor to the open-circuit drive overcomes this dilemma by limiting current through the drive transistor. Transistor Q2 provides the ...

Although this Design Idea describes a positive power supply, you can realize a similar negative-output-supply current-sense circuit using a dual NPN transistor in place of the dual PNP that the figure ...

Point out that most electronic devices run on a small current that is amplified. You’re going to build two simple transistor circuits, each using a single transistor. These circuits will allow ...

Adding a clamp circuit to the well known current-limiter protects the "pass" transistor from over-currents ... the results from a test circuit built using the resistor values quoted above, with ...

Transistors are an indispensable building ... Swedish Foundation for Strategic Research to develop new wireless circuits using nanotechnology. The newly developed transistor technology will ...

Need to switch something on or off using a microcontroller ... job of explaining the ins and outs of designing transistor control circuits. We’ve embedded his twenty-minute video after the ...

Since graphene transistors can’t be turned off, they’re more useful for RF applications than logic circuits ... and the source electrode allows current to flow through the channel.

The miniaturization of FETs faces inherent problems caused by the effect of reducing the length of the channel (the layer through which current flows between the source and drain electrodes) and ...
