If we had to pick one part to crown as the universal component in the world of analogue electronics, it would have to be the operational amplifier. The humble op-amp can be configured into so many ...

This time, we are going to take a bite of a big topic: op amps. The op amp — short for operational amplifier — is a packaged differential amplifier. The ideal op amp — which we can’t get ...

Operational amplifiers (op amps, op-amps) are general-purpose, closed-loop devices that are used to implement linear functions. They compare two incoming signals and release a third signal that is an ...

Operational transconductance amplifiers (OTA) are devices that convert an input voltage to an output current. They are primarily voltage-to-current amplifiers. Unlike traditional operational ...

After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in ...

As a service to our readers, we're providing the LTspice files used in Dr. Dyer's article on simulation of the 12AX7 and the K2-W vacuum-tube op amp. 1. The model for the K2-W is established as a ...
