FET constant current sources use JFETs and MOSFETs to deliver a load current, which remains constant despite changes in load resistance or supply voltage. A FET constant current source is a type of ...

Last time we looked at Spice models of a current sink. We didn’t look at some of the problems involved with a simple sink, and for many practical applications, they are perfectly adequate. However, ...

Current conveyor (CC) circuits are among the most common current-mode circuits and are used as critical building blocks in a variety of complex circuits. Unlike voltage-mode circuits, current-mode ...

This is the second part of a two-part series on the methodologies used to find the short circuit current duties of circuit breakers and fuses. The first part, Short Circuit Current Duties of Circuit ...

To improve efficiency in high-power applications, voltage regulators can be used in parallel to double output current capability—if a means of forcing current sharing is provided. One circuit approach ...

Properly selected components make it easier to design modern, energy-efficient power supplies. In this article we present an ...

If a charged particle beam interacts with structures of different electric conductivity in a microelectronic circuit, this leads to local changes in the electric potential at its surface. In a ...
