Linear Regulator Error Amplifier Operation
This is lab 3 of 12 in the course
Texas Instruments, and Dr. Nicola Femia | University of Salerno
In this lab, students will investigate the properties and response of the error amplifier generated by the MOSFET gate driver in a linear regulator. First, students will review the architecture and the simplified equations describing the error amplifier in DC and AC operation. Students will use the simplified model to analyze and predict the AC gain. Next, students will simulate the response of the error amplifier to the perturbations of the output voltage with respect to the desired nominal value in a regulator. Finally, they will perform experimental tests with a real amplifier to compare the results with simulation. Throughout the lab, students will be answering short questions to verify their understanding.
