Figure 2 This simple current source (Simple Source) circuit provides accuracy with a single resistor by floating the power supplies of the output stage. Isolated dual output DC to DC converters are ...

D2, though, uses a simple current sink. R3 and R4 divide the input voltage to about 1.7 V on the base of Q1. ... In this circuit, a PNP transistor sources current.

Circuit operation is straightforward. The current through the sense resistor (RSENSE) creates a voltage across it, which is then imposed across RA by the op amp. The current through RA A is subscript ...

In this installment of Circuit VR, we’ll look at a simple buck converter — that is a switching ... You can also take advantage of the fact that a constant current source will charge a ...

ATS is a piece of hardware that automatically shifts the electrical load from primary power supply to a backup or standby ...

Occasionally, the need arises for a simple current source that can be easily adjusted over a relatively wide range of current levels. The circuit shown in the figure uses a 200-kHz pulse-width ...

The conventional solutions employ concepts based on tone generation/reflection or current-source circuits. This may prove to be costly, particularly in low-cost applications like automotive designs.

A simple electric circuit learns to classify data in a creative new design that could lead to more energy-efficient machine-learning hardware. The creative new approach could lead to more energy ...
