The following is Part 1 of a four-part series. The basic one-op-amp differential amplifier consists of one op-amp and four resistors. Yet few have contemplated the depth of its complexity. It is ...

In Seemingly Simple Circuits: Transresistance Amplifier, Part 1– Approximating Op-Amps, the op-amp was approximated from a single-pole, finite gain amplifier to an infinite-gain, single-pole op-amp, ...

[Ynze] has built an audio amplifier that looks and sounds great. His amplifier uses a National Instruments (now TI) LM3886 Overture series 68 Watt power amp. The LM3886 places [Ynze’s] amp squarely in ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

How a paper substrate and biodegradable circuitry can be used for basic circuits. How the researchers fabricated and connected active and passive devices literally “on paper.” Details of their first, ...

What if a palm-sized amp could outperform larger, more expensive modules while delivering serious sound quality? Check out ...

Resistors are fundamental components in electronic circuits. Despite their simplicity, they play a central role in ensuring ...
