Linear Regulator in Open Loop DC Operation
This is lab 1 of 12 in the course
Dr. Nicola Femia | University of Salerno, and Texas Instruments
The goal of this lab is to investigate the properties of a MOSFET in DC operation, when it works as a pass device in linear regulators. First, we review the equations describing the behavior of a MOSFET in DC operation, and discuss the impact of the gate-to-source voltage on the operating point. Next, we predict the MOSFET operating region and calculate the power losses and temperature under different conditions. Then, we simulate the MOSFET using its physical model. Finally, we perform lab experiments to estimate the real value of MOSFET parameters and compare their impact on the accuracy of theoretical and simulation predictions.
