Unformatted text preview: EEE 591 Analog Integrated Circuits Laboratory Lab 6 Design and Analysis of Common Drain Amplifier Submitted by Saurabh Naik ASU ID: 1201916850 Date: 11/24/2009 Abstract: In electronics, a common-drain amplifier, also known as a source follower, is one of three basic single- stage field effect transistor (FET) amplifier topologies, typically used as a voltage buffer. In this circuit the gate terminal of the transistor serves as the input, the source is the output, and the drain is common to both (input and output), hence its name. In addition, this circuit is used to transform impedances. For example, the Thevenin resistance of a combination of a voltage follower driven by a voltage source with high Thevenin resistance is reduced to only the output resistance of the voltage follower, a small resistance. That resistance reduction makes the combination a more ideal voltage source. Conversely, a voltage follower inserted between a small load resistance and a driving stage presents an infinite load to...
