Welcome, Guest. 5 Experiment – MOSFET Common Source Amplifier The common source configuration is provided by the circuit in Figure 6. To be sure, a common source canonic cell (s) may be used in the amplifier topology, but other elements and canonic cells are also used to bolster the performance of the amplifier. This gives R D = 10/3 kohms or 3300 ohms. The frequency at which the small signal short circuit current gain of an intrinsic MOS transistor drops to unity is called transit frequency(fT). In the operational amplifier implementation of this type of amplifier, a differential pair is used as the. I'm designing a project with 0-5GHz VGA. It is commonly used at the output stage in most of the LNA design. o A lower cut-off frequency for Amplifier These capacitors can be added at input, output, and between amplifier stages. The power supplies and netlist used in PSpice simulation and numerical calculations are also indicated. * Common-Mode Input Range spice results are based on the range of input where unity feed back configuration keeps the gain of 1.
