EEE 334 Lab 5 Single Stage MOS Amplifiers Assessment Report
EEE 334 Lab 5 Single Stage MOS Amplifiers Assessment Report
The purpose of this lab is to learn about single stage MOS amplifiers. This will be
accomplished by observing DC biasing of an NMOS transistor and testing Common-Source,
Common-Gate, and Common-Drain amplifiers.
Equipment used: Bread board, DMM and ADK.
Components used: CD4007 MOSFET, 1 μF, 4.7 μF capacitor, 1.5k, 2.2k, 68k and 200k
resistors,
Experiment 5.1 DC biasing of an NMOS transistor

• Build test circuit on breadboard.
• Measure results with DMM.
• Simulate circuit in LTSpice.
• Obtain measurements with .op and transient analysis.
