Op Amps: Simulating DC Offset

DC offset is a reality that must be dealt with in precision designs. In short, it's an undesired DC output voltage that can create an ambiguity in the true DC output level. We examine the causes of DC offset and investigate issues and challenges involved with simulating it.

i am using lt spice, for the vload what is the value of it?

[@ElectronicswithProfessorFiore]

Ideally, it's 1 volt peak riding on a +1 volt DC offset (i.e., it swings from 0 to 2).

I'm amazed by how much I have continued to learn since leaving school 12 years ago when I left after completing just one year. I can predict the definitions of termed conditions and operating characteristics whether I covered the subject in school and it's foggy, or I never happened to cross it's path formally.

Glad you're enjoying it!

cool

Thank you for your work. Would you share the Name of simulator software you are using? Thank you again.

[@canos01]

TINA-TI from Texas Instruments. It's free.

Thanks...
What is a composite opamp ? ??

[@ElectronicswithProfessorFiore]

Not quite sure what you're asking. A composite could refer to an op amp made from discrete components (versus integrated).
