Experiment #4 MOSFET Common Source Amplifier Executive Summary: The MOSFET is a voltage controlled current source. It controls the amount of current flow through the Drain-Source by creating fields between the drain and source. The field works as a connection between the drain and source. In this experiment, we used MOSFET’s common - source configuration to create a voltage amplifier. The gain that we calculated for this configuration was about 13.13. The Input impedance was high: about 21.5K . The output impedance was relatively low: about 829 . The gain was inverted which was yielded through the hybrid-pi model. The gain was relatively low compared to the BJT. Objective: To experiment on design, analysis, construction and testing of a MOS field effect transistor common source amplifier.
