The source-drain MOSFET saturation current equation is: ID=12WL μN Cox [Vgs−VT]2ID=21LW μN Cox [Vgs−VT]2 There are many similarities with the linear regime current equation; however, it's straightforward to see that we lost the dependence on the source-drain voltage, retaining ...
This work presents the theory, design, and applications of a new cell for MOS linear circuit design the linear composite MOSFET (COMFET). The approach exploits the square-law saturated drain current equation of the MOSFET, and entails the design of a linear COMFET circuit, with both its ...
In the linear region (0 < VDS < VGS –Vth), the drain-source current is: IDS=K((VGS−Vth)VDS−VDS2/2)(1+λ∣VDS∣) In the saturated region (0 < VGS –Vth < VDS), the drain-source current is: IDS=(K/2)(VGS−Vth)2(1+λ∣VDS∣) In the preceding equations: K is ...

For the linear regulator shown in Figure 1, power loss and efficiency are defined by Equations 1 and 2. Power Loss = (VIN – VOUT) × IL (1) Efficiency = VOUT × IL VIN × IL = VOUT VIN (2) In the ideal switching regulator shown in Figure 2, the current is zero when the ...
Suppose we have a MOSFET with an 8 ns minimum turn-on time driven with a gate driver. The gate driver is sourcing 2 A of current into a gate with 100 nC total charge, and the gate driver voltage rise time is 22 ns. Using the above charging equation, the charging time is: ...

Linear/Ohmic Region –It is the region where the current across the drain to source terminal enhances with the increment in the voltage across the drain to source path. When the MOSFET devices function in this linear region, they perform amplifier functionality. ...
