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, ...

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 ...

We were recently tipped off to quite a resource — on the Texas Instruments website, there’s a page where you can view and ...

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, ...
