Low-cost integrated resistor networks can be used to implement a low-parts-count two-op-amp differential amplifier with low common-mode gain. Integrated onto a common substrate and processed together, ...

The three circuit coefficients, T i+, T i-, and A 0 are part of the one-op-amp diff-amp model as developed in Part 1 of this article. By substituting for v + and v – in the v O equation and ...

LTspice simulation of the K2-W Vacuum Tube Op Amp’s design reveals the mad science that created a commercial revolution in 1950s and 1960s analog computing. The K2-W's first-stage differencing ...

Unveiled as a duo, the 2.5-GHz LMH6554 wideband differential amplifier and the 10-bit, 2 Gsamples/s ADC10D1000 a/d converter specify what the company states are the best ENOB, SFDR, and gain-flatness ...

A differential probe, a device for measuring the voltage between two points in a circuit rather than the voltage between a point and ground, it an extremely useful addition to any electronics bench.

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...
