Although current-feedback operational amplifiers (op amps) have been on the market since the 1990s, the current-feedback fully differential amplifier was not introduced until 2007. There are several ...

An electronic circuit that amplifies the difference between two voltages. With one regular input and one inverting input (+ becomes -, - becomes +), it multiplies the difference by a constant factor.

The transfer function of this amplifier is: With R1 = R3 and R2 = R4, Equation 1 simplifies to This simplification can be a quick way to approximate the expected signal, but those resistors are never ...

Fully differential amplifiers have grown in popularity because of their low distortion, excellent noise rejection, and the simplicity of interfacing them with differential analog-to-digital converters ...

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.

Accurately measuring current flow is a standard requirement in several applications (Fig. 1). Depending on the specific need, the options available to designers can include discrete designs assembled ...

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 ...
