One of the more common building blocks of a voltage controlled amplifier (VCA) is a differential pair amplifier. For a VCA configuration, the (top) two bases receive a control voltage for gain control ...

The EL5120T is a high voltage rail-to-rail input-output amplifier with low power consumption. The EL5120T is a single amplifier that exhibits beyond the rail input capability, rail-to-rail output ...

With Megger’s new VAX020 high voltage amplifier, it is now possible to reliably assess insulation condition using proven dynamic frequency response (DFR) techniques, even in extreme high interference ...

The circuit in Figure 1 sinks a constant current (ICE3) through Q3’s collector and emitter. This design is balanced so changes in Q3’s base-emitter voltage (VBE) don’t affect the current sink’s ...

This file type includes high-resolution graphics and schematics when applicable. A coulomb counter can measure charge that flows into or out of a battery, and small, dedicated ICs can directly ...

TREK, INC. has announced a new High Voltage Power Amplifier - Trek Model PZD700A - that offers wide bandwidth and additional features important in piezoelectric driving, electro-optics, MEMS and ...

If you ever wanted to build your own tube amplifier but you were intimidated by working with high voltages, [Marcel]’s low-voltage tube amp design might spark your interest. The design operates with a ...

The PZD700A is a high-voltage DC-stable piezo driver/amplifier. The signals generated by the PXI-5402 Function Generator are amplified by this system for our high-voltage actuated experiments. Output ...

FEMTO’s logarithmic wideband voltage amplifier HLVA-100 has a wide dynamic range of 0dB to 80dB, with DC coupled input and a fast rise/fall time of 5ns for a 40dB step. The noise for the device is ...

Much like vinyl records, tube amplifiers are still prized for their perceived sound qualities, even though both technologies have been largely replaced otherwise. The major drawback to designing ...
