Demand for voltage-controlled current sources (VCCSs) and multipliers in a wide spectrum of electronics and communication devices always seems to exist. The multipliers employed in circuits like the ...
Editor's NoteThe electric power industry is emerging as a driving force for the Korean economy, following automobiles and semiconductors. For a long ...
Many precision current source designs are available, but simple arithmetic for component values to tailor them for an ...
Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...
The LM4041 has been around for over 20 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this classic device also found its way into alternative ...
We have been looking at the history of some HVDC devices such as the mercury-arc valve and the thyristor valve for the past few months. The mercury-arc valve made HVDC transmission possible (1950s), ...
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 ...
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 ...
