Download Understanding Operational Amplifiers: Goals and Circuit Analysis - Prof. Aurangzeb Khan and more Study notes Electrical and Electronics Engineering in PDF only on Docsity! 1 Chapter Goals-9 • Understand behavior and characteristics of ideal operational amplifiers (op amps) • Study non-ideal op-amp behavior • Demonstrate circuit analysis techniques for ideal and non-ideal op amps • Characterize inverting, non-inverting, summing and instrumentation amplifiers, voltage follower and integrator • Learns factors involved in circuit design using op amps 2 If R2=0 or R1=∞ Demonstration of the Voltage Follower as a perfect buffer By voltage divider rule, ⇒A severe loading effect or attenuation. RS<< input impedance of op amp ⇒VO ≅ VI ⇒ Loading effect is eliminated i=0
