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 ...

Basic LM317 current source I wondered if the subcircuit consisting of the LM317 and resistors Rs and Rc could form the basis for such a circuit if it were driven from a suitable control current. In ...

When it comes to electrical circuits, there’s a lot to remember and understand. We've got you covered with this Intro to Circuits BBC Bitesize guide.

Electrical Circuits and its Components The voltage from a battery, or a transformer, drives a direct current (DC) through a defibrillator circuit, leaving the charge to flow only in one direction ...

Linear Technology's recently introduced LT3092 is a 2-terminal programmable current source, typically defined as a circuit that delivers or absorbs current.

These simple current sources and sinks are pretty useful. However, there are some limitations and there are circuits we will look at in the future that try to mitigate those limitations.

The op-amp circuit in question. He starts with the current source, a simple circuit of two diodes, a resistor, and a transistor that sets the bias for the two-transistor differential amplifier.
