In this lab, students will investigate the MOSFET in AC operation, which is of interest in linear regulator applications. First, students will review the equations describing the MOSFET behavior in an AC operation, and then students will use a model to analyze and predict the sensitivity of the output voltage from a gate driver voltage at different frequencies. Students will simulate the response using Multisim Live and take measurements. Students will compare the measured result with simulated and theoretical results. Throughout the lab, students will answer short questions to confirm their understanding of the topic.
After completing this lab, students will be able to:
Given the MOSFET load resistance, DC voltage and a DC gate driver voltage, calculate the magnitude and output voltage AC perturbation determined by AC perturbations injected on source and gate driver voltage, with specified units and decimal digits, by applying the appropriate theoretical formulae.
Given the MOSFET load resistance, DC source voltage and a DC gate driver voltage, simulate the operation of MOSFET to analyze the sensitivity of the output voltage with respect to AC perturbations injected by the source and gate driver voltage, with specified units and decimal digits, to determine the accuracy of theoretical predictions.
Given a MOSFET, a dynamic power supply, a load resistor and dynamic gate driver, analyze experimentally the output voltage AC perturbation determined by AC perturbations injected on source and gate driver voltage at different frequencies, with specified units and decimal digits, to verify the consistency of theoretical predictions and simulations.
