In this region, both DGMOSFET inner transistors operate in either linear or non-linear region each. Gate-to-gate interelectrode spacing influence is taken into account in I D– V DS modelling with the effective parameter m eff = μ eff2 L eff1/ μ eff1 L eff2. For low bias ...
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 ...
If, in the Faults settings, you set the Failure mode parameter to Parameter shift, the MOSFET fails due to the aging of its components. This equation defines the value of the shifted parameters: Parameter(t)=Parameterfaulted−(Parameterfaulted−Parameterunfaulted)sech(t−tthτ), where tth...

(2) A better and more accurate reading of the avalanche energy can be obtained by measuring instantaneous voltage and current in the device and integrating as described in the following equation: t2 EAS = V(AV)DSSt x IASt x dt (3) t1 For further reference, figures 15...
The last equation (VTEXT) is the x intercept of tangent fit of the ID-VG curve at the maximum GM point. Figure 5 illustrates the Formulator Tool interface. Figure 5. Model 4200-SCS’s Formulator Tool interface Once those parameters are calculated from individual tests, they...

PGATE = QG(TOT) × VG × fSW (5) There are also general gate losses as shown in Figure 7. The MOSFET effect on the gate-driver IC, or a pulse- width modulation (PWM) controller with an integrated gate driver, add to the power-dissipation losses. As shown by Equation 6, gate-...
DUTY CYCLE OPERATION When operating in the duty cycle mode, the maximum drain voltage can be increased. The maximum operating temperature is related to the duty cycle (DC) by the following equation: TC = (VDS x ID x DC x RqCA) + TA The maximum value of VDS applied when operating in ...
3. THE IMPEDANCE OF THE GATE CIRCUIT To turn on a power MOSFET a certain charge has to be supplied to the gate to raise it to the desired voltage, whether in the linear region, or in the "saturation" (fully enhanced) region. The best way to achieve this is by means of a voltage ...
