The Precision Rectifier: Op-amp basics, episode 5

VERSION WITHOUT BURNT-IN CAPTIONS WILL BE AVAILABLE AT    • The Precision Rectifier: Op-Amp Basics Epi...   Op-Amp Basics Episode 5: The Precision Rectifier Please join me in supporting the 'Get Fed Up!' campaign at Save the Children. http://support.savethechildren.org/go... In this episode, we look at precision half-wave and full-wave rectifiers: op-amp circuits to clamp an input signal to the ground or take its absolute value. In the process, we learn about op-amp slew rate and how it limits the performance of circuits that need to make sudden voltage changes. Schematics of all the demo circuits can be found on the project GitHub: https://github.com/kennykb/kevins-cav...
