WebYour equations are approximations to the capacitance seen between G-D and G-S of a mosfet in different regions of operation and they are derived based on the physical characteristics of the mosfet. Keep in mind that the physical mosfet is a symmetric device. In the case of N-MOS, the terminal with a lower voltage is called the source (since it … Web1. It can limit the gain of a MOSFET linear amplifier. In Lecture 21 we will learn that we achieve maximum gain from MOSFETs operating in strong inversion when we bias as …

WebA MOSFET is a MOS transistor and is essentially consist of a MOS capacitor and two diffused or implanted regions that serve as ohmic contacts to an inversion layer of free charge carriers with the semiconductor-silicon dioxide interface. Figure 5.4 illustrates the 2-D structure of an n-MOSFET.
