I am working on the design of efficient voltage regulator for Intel mobile processors such as Intel Atom. I read about the IMVP technique for reducing power consumption of processor. It depends on changing the processor Core voltage depending on the processor operation modes.
I searched a lot...
I agree with Easyrider83. Why did you divide the triangular signal by 2 then you amplify it by 2 ? the circuit do like multiplying the triangular signal by (2/2) which mean 1.
Please try removing the non-inverting amplifier circuit because there is no need for it. Or try amplifying the...
Hi all,
I have a dc signal that contains a sawtooth-shaped ripple. I need to design a differentiator circuit that differentiate the sawtooth ripple and produce a square-wave signal. I tried using the conventional inverting op amp differentiator circuit but my circuit has not negative supply...
Another thing, how can you test the phase margin and gain margin if there is no feedback at the circuit ?
Generally, the stability issue appears only at closed loop systems. If your system is open loop, this mean that it will be always stable.
I think that you shouldn't use Vsin, instead of this put a Vdc and evaluate 1V for the ac voltage attribute inside the symbol. If there is Vac at you project it will be useful also.
try this and I think that your problem will be solved
As leo said, 0.25um devices cannot withstnad 5v. The maximum Vds and Vgs for these devices is 2.5v. there are 0.25um technologies that have devices withstand 3v and up to 3.3V.
Hi
I think that you will find what you need at the attached paper.
In this paper you will find how to calculate the minimum inductor and capacitor values. The inductor value is determined based on your switching frequency. The minimum value of inductor is the value that make buck converter...
I agree with FvM, Ids*Vds over one period is the total losses including conduction and switching losses. You don't need to calculate them separately. You will need to calculate them only if you need to know which one of them is higher (conduction or switching) to reduce at and achieve high...
what do you mean by transistor description ?
the Vgs and Vds voltages that you apply are the main factors that determine whether your transistor is operating in the saturation or cutoff region.
you can check this application note:

Hope this help

Tell me what you are trying to do ? are you trying to design a transimpedance amplifier ?
Generally, most of the effects that can be occurred due to process corner appear at the digital circuits design. If you need to design a fast digital circuit, you should take care for the effect of slow corner (for both NMOS and PMOS).
Their effect on analog circuits will appear and become...
well.
The output capacitor really affect the transient response for buck converter.
The output capacitor and inductor values affect the double pole of LC low pass filter and determine the locations of these poles.This ,off course, determine the final shape of the frequency response for the...
