AB  - Operational Amplifiers are one of the important topics in many electronic circuit courses. Although it is one of the most taught subjects,  the model for the application of operational amplifier with negative feedback configuration is incomplete in most of the electronics textbooks. The closed loop gain for the non-inverting amplifier is given as AoL/(1+βAoL), while the closed loop model for the inverting amplifier is not given in most of the textbooks. Instead usually nodal analysis is used to derive the expression for the inverting amplifier gain. Using different derivation paths causes confusion for the students, as the comparison is not provided from the same point of view. 
The constant gain-bandwidth product is mentioned for the closed loop frequency response for the amplifier, but it is not clearly specified that it only applies for the non-inverting amplifier configuration. The missing details usually cause misconception for the students and mismatch between the lab results and their expectations. The paper presents a detailed lesson with lab procedure on operational amplifiers covering the feedback models for the inverting and non-inverting amplifiers as well as their frequency response.
