Circuit delivers high voltage swing from lower supplies: 12/12/2002  EDN - Design Ideas /   The need for higher voltage swings in applications such as test-and-measurement instruments is constantly increasing, but the power supplies impose limitations on the operational amplifier rails make the high-voltage need a challenge for designers. How do you deliver high-voltage swings to a load without increasing the voltage levels of the power supplies of the operational amplifier? In other ..

COCKCROFT and WALTON VOLTAGE MULTIPLIERS: Here are some applications of the Cockroft-Walton voltage doubler circuit for generating high voltages from a low voltage AC source. The circuit is quite practical for generating thousands of volts (or more) or just a few volts at high current.

Virtual zener circuit simplifies high voltage interface: 03/20/03  EDN-Design Ideas / This design for a photonic switch needs more than approximately 70V at the cathode of a duo-lateral optical position-sensing device. This voltage gets speedy response at longer wavelengths, such as 980 nm. The circuit uses fast transimpedance amps, "floated" at 70V. Two "virtual-zener" circuits step down the high-voltage signals for subsequent processing in a ground-referred differential-amplif.....
