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 ...
Despite the monolithic op amp being older than SPICE simulators, comprehensive op-amp SPICE modeling left a lot to be desired—until now. LTspice simulation of the K2-W Vacuum Tube Op Amp’s ...
What I’d stumbled upon was a chopper amplifier, a slightly ungainly and long superseded solution to the problem of DC amplification from the days before ubiquitous integrated circuit op-amps.
A developer has built a laser galvo-based vector display featuring a custom signal conditioning and thermal management system that leverages a low-cost galvanometer for high-speed vector rendering.
