Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...

We believe the most likely path for Fed policy in 2026 is for the central bank to bring rates down from the current range of ...

Abstract: A voltage-controlled pulsed current source (VCPCS) capable of generating current pulses with four different waveforms in the time domain is presented in this article. These waveforms are the ...

A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V.

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...

The common source amplifier is one of three basic single-stage amplifier topologies. The MOS version functions as an inverting voltage amplifier. The gate terminal of the transistor serves as the ...

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 ...

The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its ...

We have examined voltage sources, and now we can examine their less-known but necessary complement, the current source. Figure 1. The schematic symbol for a current source can be either a circle with ...

Voltage and the lesser-known current sources provide critical IC, circuit, and system functions. Voltage sources and their complement to current sources are essential elements of many systems, ...
