An introduction to analog circuit design* Part 2: Operational amplifiers

As the name implies, if we finally put together all the elementary blocks above (transistors, current mirrors, current sources, differential stages and buffers) we finally come to something usable, ...

Circuit VR: Sink Or Swim With Current Sources

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

What’s All This JFET Constant-Current Stuff, Anyhow?

Download this article in PDF format. When you connect the gate to the source of a JFET (junction field-effect transistor), it becomes a two-terminal current source. The current that will flow is ...

An introduction to analog circuit design* Part 1: Transistors and Elementary Circuits

Modern circuit design is a “mixed signal” endeavor thanks to the availability of sophisticated process technologies that make available bipolar and CMOS (Complementary Metal Oxide Semiconductor), ...

2-Terminal Current Source Boasts High Accuracy, Programmability and Stability

Before the LT3092, the simplest current source was merely a voltage source with a resistor in series feeding the load resistance. Assuming the load resistance is much smaller than the series resistor, ...

Current source rectifier confusion

The LM334 is not only an adjustable current source, but it is also a rectifier. Right on the front page of the TI data sheet are the words: “Reverse applied voltages of up to 20V will draw only a few ...
