How to calculate variations in power supplies due to second order effect

In this video, I show how to calculate variation error in power supplies due to second order effect in the error amp such as Vos, Ibias, and Ioffset currents. I show how to derive a mathematical equation and a SPICE model and show how both will predict your error due to these op amp parameters. Question, commnets, or request for SPICE model can be sent to [e-mail]. If you find this video useful, please subcribe, share and like.

Hi Robert, great video! really appreciate the effort you put in. Can you explain where Vth/Vref = Vactual/Videal is coming from?

Robert thanks for your videos, I'm from Colombia and my English is not good and I can't understand some things, if you are so kind, please recommend me a book or document where I can study the subject and understand your calculations, blessings.

Hola Alvaro, tengo un video donde recomiendo libros de Fuentes de poder (Power supplies). El video esta aqui, kzbin.info/www/bejne/q4jJgKGBht-ga7s Para entender como trabajan Op Amp, el libro que recomendo es por Franco Sergio. www.amazon.com/Operational-Amplifiers-Integrated-McGraw-Hill-Engineering/dp/0078028167/ref=sr_1_1?keywords=sergio+franco&qid=1576852267&sr=8-1 Hojala que esto te ajude.
