IN a paper read before the Institution of Electrical Engineers on March 6, D. C. Gall describes the design and behaviour of a direct-current amplifier, entirely alternating-current mains-operated, and ...

The electrification of vehicles has spurred an increased demand in accurate current measurement in new electronic drive systems, such as traction inverters, DC-DC controllers, battery managements ...

Over the years there have been many different audio amplifier designs which have found favour for a while and then been supplanted by newer ideas. One of them has crossed the bench of [Jazzy Jane], it ...

Using a resistor and voltage amplifier across it for current sensing presents a conundrum. On one hand, it appears to be near-trivial application of Ohm’s Law via I = V/R. It certainly looks easy: A ...

Texas Instruments (TI) rolled out its first current-sense amplifier to integrate a high-precision, low-drift shunt resistor, which can deliver highly accurate measurements over a wide temperature ...

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 ...

TOKYO--(BUSINESS WIRE)--Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has added “TC75S102F,” a new CMOS operational amplifier featuring industry-leading [1] ultra-low current ...

Vishay has introduced a precision isolation amplifier with 5kVrms isolation test voltage and 150kV/μs typical (100kV/μs min) common-mode transient immunity: VIA0050DD. “Isolation amplifiers in the VIA ...

Here at Hackaday we’re no strangers to the colorful glow of LEDs. But what if there was more to appreciate beneath the surface? Back in 2011 [Windell] over at Evil Mad Scientist dug into a certain ...
