Design of common source amplifier
WebThe gain (inverting) of a MOSFET Common Source amplifier is a function of its output impedance (Zo) and its transconductance at the bias point (y fq) and is defined by the equation: Av = - y fq Zo By analyzing the AC equivalent model of a properly decoupled and bypassed Common Source MOSFET amplifier (see Fig 1 below), Figure 1. WebThis topology amplifier is known as a common source amplifier The equivalent small signal circuit for the amplifier is shown to the extreme righnt and is most easily understood by remembering that the current in a source follower is given by . where . Since this current is unchanged by the addition of the drain resistor, the output voltage will be
