Current sources are widely used in industrial control systems to transport analog process signals over long distances, but they are less widely used than voltage sources. This post loosely reviews the ...

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 two methods for testing DC-DC stability. Frequency behavior with buck VM and CM architectures. Compensators for VM and CM architectures. Aligning the time constants of the LC filter to close the ...
