Lecture
This lecture covers the applications and configurations of operational amplifiers (AO), including open-loop and positive feedback applications, as well as the summary of operational amplifier characteristics. It also discusses the concepts of followers, oscillators, comparators, and zero crossing detection. The lecture explains the principles of inverting and non-inverting amplifiers, highlighting their graphic variants and applications. Additionally, it explores the concept of negative feedback applications and the superposition principle in amplifier circuits.
