Drain current maximum

From these two runs we determined that the minimum drain current occurs with the model jMIN and its value is 5.6001 mA. There is no general rule to determine whether the maximum or minimum model of the jFET will give you the maximum or minimum of the output variable. In general, you will have to make multiple runs to find the minimum and multiple runs to find the maximum. 

We will now find the maximum drain current of the circuit in Section 9.F.I. The procedure is exacdy the same as in Section 9.F.1, except that we must specify PSpice to find the maximum value. Follow the procedure given in Section 9.F.I, but use the Monte CarlO/WOfSt-Case Output File Options dialog box settings shown below ... 

Figure 10 illustrates the short-term dc stability of the devices (Mackenzie et al, 1983). The output characteristics of one FET are shown for 10 successive scanning cycles of VG from —10 V to +45 V and back. The gate voltage was scanned in both directions at a rate of about 0.5 V sec-1. The traces show remarkably little drift or hysteresis in fact, the maximum variation in VG is approximately 0.4 V for a given value of source-drain current. 

The maximum load current in our example is therefore 10 A, and is Idmax in Figure 5-2. If we plot the drain current and drain voltage with respect to time, we see that the crossover time, tcross, is 10 s here. Note that this time is by definition the time for both the voltage and the current to complete their transitions. 

However, a plot of hydrogen sensitivity (defined as the drain current change over the initial drain current) versus bias voltage shows different characteristics for forward and reverse bias polarity conditions at 500 ppm of H2, as shown in Fig. 5.11. For the forward bias condition, there is a maximum sensitivity obtained around 1 V and further increase of bias voltage reduces the sensitivity. 

Fig. 19.19 Pacemaker output settings for lowest current drain and maximum longevity induction of an endless loop tachycardia during an atrial capture threshold test in a patient with a Pacesetter Affinity DR pacing system. The automatic PMT detection and termination algorithm recognized the tachycardia and promptly terminated it. Meanwhile, the recording provided details as to the tachycardia interval and the retrograde conduction interval providing guidance as to programming the PVARP.

Figure 6.8 depicts and Ig plotted versus Eq for various values of V calculated on the basis of Equation 6.10, indicating that the maximum source-drain current for gate measurements occurs when Eq = E° and V is sufficiently large (>0.25 V at room temperature), yielding I = nFAk d /w. 

In Fig. 16 the simulated output characteristics and drain conductances are depicted at a gate voltage Vgs = -6 V for different contact conditions. It can be seen that a nonlinear drain current increase and the resulting maximum of the drain conductance at finite drain voltage occur always if at least one contact has a work function

drain current is lower when the double layer contact acts as source. From these results one can conclude that the low chromium work function causes the nonlinear increase of the drain current. But, in contrast to the measurements, the maximum of the drain conductance occurs at almost the same drain voltage for the double layer contact as source or as drain. Additional simulations...
