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 ...

If you’re the sort who finds beauty in symmetry – and I’m not talking about your latest PCB layout – then you’ll appreciate this clever take on the long-tailed pair. [Kevin]’s video on this topic ...

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.
