This experimental (3) transistor class A audio power amplifier delivers 25mW into an 8Ω load, or 50mW into a 4Ω load using only a 1.5V power source. At such low voltages, there are many issues to ...

Piezoelectric effect is when certain solid material is compressed under mechanical stress, and it develops a voltage potential by accumulating electrical charges. French physicists Jacques and Pierre ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...
