USB chargers are everywhere and it is the responsibility of every hacker to use this commonly available device to its peak potential. [Septillion] and [Hugatry] have come up with a hack to manipulate ...
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 ...
If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.
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 ...
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 ...
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 ...
In the world of power electronics, most instrumentation-grade devices contain a source function and a measurement function. A high-performance power supply is a one-box solution that includes 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 ...
The electronics industry is seeing a move toward higher voltages and currents to deliver sufficient supply and charging power in products ranging from handheld cellphones and tablets to workstations.
