Shah, V. Lee, L. Dai 2 Lab Objectives This lab will familiarize you will the properties and operations of operational amplifiers. In this lab we will use the LMC6482 operational amplifier to implement several different practical configurations of the operational amplifier. In the pre-lab, you will first simulate the different configurations for the operational amplifier: inverting, non- inverting, comparator mode, and Schmitt trigger. In addition, we will also analyze the instrumentation amplifier. Make sure to bring your circuit schematics with you to the lab. During the lab, you will build the circuits that you simulated in the pre-lab and explore the non-idealities of real world implementations. Finally, in the post-lab, you will use what you learned in the pre-lab and lab components to design and synthesize a light gate. Pre-Lab Component In this lab we will be working with a strange device known as the operational amplifier. The operational amplifier is used extensively in circuit applications all throughout the field of electrical engineering so it would be worth your while to master the art of using the operational amplifier. Unfortunately, understanding the internal circuitry of the operational amplifier is beyond the scope of this course (see EE140). Operational amplifiers are (obviously) used to amplify electrical signals by a certain factor known as the gain. In theory operational amplifier have infinite gain; however, practical operational amplifiers have very large gain, which for a majority of DC applications is sufficient. Later, in the course we will learn about the limitations and finite gain bandwidth for AC applications but were not concerned about that at the moment. Because the gain of the operational amplifier is very large, we use negative feedback to control the gain of a given configuration....
