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 ...

Voltage conveyors and current conveyors represent two pivotal active building blocks in contemporary analog circuit design. Their unique signal processing capabilities allow for efficient voltage ...

Nullator, norator, and nullers all started out as theoretical circuits. A nuller is the result of the combination of a nullator and a norator, which forms a network element with a transmission matrix ...

Switch-mode power supplies can use digital current-mode techniques for protection against peak currents, magnetic field "ratcheting," and input-voltage variations. Digital control of switch-mode power ...
