A new formula is derived for the linear region where the role of important parameters is easy to interpret. It is discussed that the parameter n may differ with devices. When optimized, an average fitting error as small as ≈0.4% is achieved over the entire linear region....
linear region1/f noiseunified modelThis paper presents results of low frequency noise measurements for a Dual-Gate MOSFET (DGMOSFET) in linear region. DGMOSFET working conditions are chosen in order to set both inner transistors in linear regime. Results are discussed with the use of the ...

Remember the equation for saturation-mode drain current: ID=12μnCoxWL(VGS−VTH)2ID=12μnCoxWL(VGS−VTH)2 Drain current is directly proportional to the width-to-length ratio, and thus we can increase or decrease IBIAS simply by making Q2’s W/L ratio higher than or lower than that ...
For the switch MOSFET shown in Figure 6, a lower gate charge (QG) in Equation 5 enables lower power loss and a faster switching time; however, this contributes to more parasitic turn-on of the rectifier MOSFET. A happy medium can be obtained in the design to accommodate these trade-offs...
