and integrators via complex patch panels. The use of analog computing was on the way out, being displaced by digital computers, so I can’t say I got much out of the computing part of the class. I did ...

If you have read my first blog, you may have noticed that I really like op amps. My primary expertise lies in designing them, but I’m also intrigued by clever op-amp application circuits ... that ...

In real life, it’s a bit more complex ... in the op-amp input.1 C9 and C10 can be replaced by adjustable shunt regulators and R3 and R4 by current sources or followers. Then the circuit will ...

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 is one of the reasons why so many designers have shied away from using non-inverting inputs in their op-amp summer circuits. You could set up a spreadsheet to crunch the numbers, but that ...

This would make a great demo project to show your friends and ... and this is one of them. The circuit consists of two op-amps that amplify the output of two phototransistors, which control ...
