Estimates derived from thermal simulation; actual values depend on the application. 2.The differential pair is all about balance. Thus, for optimal performance the resistors and MOSFETs must be matched. This means that the channel dimensions of both FETs must be the same and that R 1 must equal R 2. The resistance value chosen for the two resistors will be referred to as R D (for d rain resistance).NMOS Transistor Circuit. The NOT gate design using PMOS and NMOS transistors is shown below.

Likewise, when V IN is LOW or reduced to zero, the MOSFET Q-point moves from point A to point B along the load line. The channel resistance is very high so the transistor acts like an open circuit and no current flows through the channel. So if the gate voltage of the MOSFET toggles between two values, HIGH and LOW the MOSFET will behave as a "single-pole single-throw" (SPST) solid state ...
