MOSFET Small-Signal Analysis Steps - KU ITTC

This is called the "small-signal model". The small signal model is dependent on the DC bias currents and voltages in the circuit (the Q point). Changing the bias moves the operating point up or down on the curves, thus changing the equivalent small-signal AC resistance, gain, etc. seen by the signal. small-signal modeling of rf cmos a dissertation submitted to the department of electrical engineering and the committee on graduate studies of stanford university in partial fulfillment of the requirements for the degree of doctor of philosophy jaejune jang august Steps for MOSFET Small Signal 3/7 Jim Stiles The Univ. of Kansas Dept. of EECS Step 3: Carefully replace all MOSFETs with their small-signal circuit model. This step often gives students fits! However, it is actually a very simple and straight-forward step. It does require four important things from the student— 3. Small Signal Model After determining the DC Bias Point, we are usually interested in the AC property of the circuit. Therefore, we need the small signal model to analyze the circuit. The simplified small signal model ignores the effect of Vbs and capacitors between each terminal. Figure 2.
