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 ...

The final part of this series will start with bias servo circuits for automatic set up. The FETs pinch off or threshold voltage can vary widely for the same part number. Depending on the fabrication ...

I/O Buffer Information Specification, or Ibis, models have become an important signal-integrity simulation tool, because designers prefer the easy access and simplicity these models provide. Ibis ...

Linear voltage regulators are key components in any power-management system that requires a stable and ripple-free power supply. A subset of linear voltage regulators is a class of circuits known as ...

(MENAFN- EIN Presswire) EINPresswire/ -- The aim is to provide users worldwide in the energy supply and industrial sectors with an electronically controlled voltage source for precise testing and ...

Ameren Transmission has energized the first two of four innovative upgrades to ensure its grid remains stable as the utility transitions to clean energy sources. Known as Static Synchronous ...

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.
