WebApr 16, 2024 · The common source amplifier is the basic field-effect transistor technique that normally works as a voltage amplifier. The simple method to know configuration is either a common drain, gate, or source to find the direction of signal from it entering and leaving. The other terminal remains common. Web• In common -source amplifier, voltage gain rolls off at high frequency because C gs and C gd short circuit the input • In common -source amplifier, effect of C gd on bandwidth is amplified by amplifier voltage gain. • Miller Effect is the effect of capacitance across voltage gain nodes magnified by the voltage gain
