Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and… ...

This Design Idea is a two-wire current regulator that strikes a good balance between performance and parts count. Employing three transistors, three resistors, and one LED, it achieves good regulation ...

If you look at the schematic of what’s inside a typical op amp, for example, you’ll see current sources and sinks are used on nearly all the amplifying transistors.

Source-gated transistors – SGTs – are uni-polar – they only need n or p-type semiconductor, not both. The research team built two two-transistor building blocks: A polysilicon gain block with the ...

However, as a current amplifier (which generally implies operation from a high impedance signal source) the behavior of a BJT is vastly more linear than when used as a voltage amplifying stage, for ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

In summary, switching transistor Q1 on results in a moderate increase, no change, or a large increase at U1’s output, depending on whether the thermocouple is in no-fault, short-circuit, or open ...

SGT transistor promises denser circuits Researchers from Surrey and Cambridge universities and the National Research Institute in Rome have demonstrated the use of a pioneering circuit design that ...

Another current limiter uses a P-channel MOSFET as a pass device, with gate voltage controlled by a transistor that amplifies the R SENSE voltage drop. 3 This circuit experiences a drop as low as ...

The organic flash memory exhibits long retention characteristics (current change less than 10% after 10 4 s), leading to the long-term stability of the 3D T-inverter. We believe the 3D T-inverter ...
