Re: differential amplifier..friends plz help ...URGENT
en, 0.7V is a Vt only.
Here 's reqirement is not a Vt, it need a Vgs.
So , it's a Vt + Von(or over drive)
So, Vinmin=Vt + Von + Vds = 0.7+0.3+0.3=1.3
I'm sorry that I didn't fully understand your mean before.
I think this is a normal problem in parameter sweep and transient simulation.
If your circuit is a DC operation circuit no switching, you can easily get the curve from DC parameter sweep simulation.
If your circuit is a switching...
pulse skip burst
You can easily find these two control mode in some DCDC 's datasheet.
TI's tps62200 , LTC3406.
The pulse skipping is one of the regulator's control mode, it was not "occurs when the "supposed duty cycle" is equal or smaller that the minimum one offered by the controller...
pulse skipping mode operation
pulse skipping = stop switching , change the pulse density.every clock cycle is the same frequency as normal working.
burst mode is LTC patented control mode.more like real PFM control. They use Current Limit to stop one pulse .The total switching will less then...
