Having hacked away with high voltage for many years I’ve ended up using a large number of very different high voltage sources. I say sources and not power supplies because I’ve even powered a corona ...

A power supply’s source, in actual use, is never ideal. The real behaviour, including parasitics, needs to be considered to build a reliable power system. When we use power supplies, we ensure that a ...

An analog- or a mixed-signal lab cannot have too many voltage sources. A simple, reasonably high-precision voltage source can set bias points in an op-amp circuit, tweak the feedback node of a power ...

The low-noise MeasureReady™ 155 precision current and voltage source combines excellent performance capabilities with an unprecedented simplicity that provides both materials scientists and engineers ...

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 ...

Many embedded systems require a stable, low-noise DC reference. This reference can be a stable current or voltage source. These references are used in many ways. Some typical uses are listed as ...

A power supply’s source, in actual use, is never ideal. The real behavior, including parasitics, must be considered to build a reliable power system. When we use power supplies, we ensure that a dc-dc ...

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 ...
