Can anyone pls explain to me in digital layout what are the factors that affect 1) Timing (causing timing violations) 2) power 3) area (if i have missed on any other factor that is considered while doing digital layout design kindly include that too pls) For a analog layout with scaling technologies so many issues are considered while doin
Hi, I've a completed layout in ADS and am wanting to produce the artwork for creating the micro strip circuit. Our lab has a convoluted process of exporting dxf and colouring it in and scaling it a few times. After some playing with the artwork generation in ADS, I've not produced anything usuable; to scale or even the right colour (black).
What is the peak to peak voltage range and the frequency of the AC signal? Essentially, you will need to signal process by scaling and level shifting the AC signal into the DC range of the ADC0808. BigDog
CMOS process provides lower power consumption and is easy to scaling down. Gate of MOS needs much lower driving current than base current of bipolar. scaling down increases CMOS speed.
Depends on your process and power supply voltage. Perhaps the following document may help you down-scaling:
This process is called analog scaling and it can be reasonably easy done with opamps .. Here is an appnote: scaling DC Input Voltages Give it a read .. IanP :D
Hi dears, I need scaling factors for calculating delay time changes,Power consumption, bandwitdth and chip area from 0.6um & 0.18um (TSMC) process to 90nm (UMC) process. I search ITRS ( ) but no topic find about it.:cry: thanks for your help.:D Regards
All, What happen to the variation of the design (say OSC) if I use 1.8V VDD for my 3V transistor. One thing for sure we need to watch out for headroom. If the headroo is OK, what else can contribute to the high variation of the design across temp, process and VDD. (PVT) thanks in advance
can any one tell me wat is theoretical utility of image gradient in image scretching or scaling process
The voltage range of analog output signal is 880mv to 3.5V. But the ADC input range is 0 to 2.5V. Should I use voltage clipping, voltage divider or use AC coupling to process input signal for matching ADC input range? Thanks.
Here some scaling rules to consider: A flash scale by a base of 8!!! P(flashADC)~8^n Why?. Number of comps by 2^n. The area of each by (2^n)^2=4^n. You can consider ADC process as weighing using unprecise weights and a noisy balance. If you make a binary decision which weight replace you can make errors as long the scale ratio between t
I tried to simulate just a simple circuit of two inverters in cadence: one inverter from each process. My first issue was the scaling: one process scales units to um and the other doesn't so it is not able to recognize the device size as it is in the correct range for the model!! How do I deal with that?
If your circuits are all 3V devices, there will be no scaling effects from 0.18um process to 0.13um process. If your circuits are all 1.8V device, there will be some scaling effects from 0.18um process to 0.13um process. Usually, there will be about 40~50% shrink for all digital (...)
There are lots of critical issues that troubled in this technology. i.e Metal Resistance metal width are getting smaller this will be accompanied by increase in resistivity. scaling problem with the VIAs and CONTACT's also the resistance accompanied by them will become higher, plus the mask preparation will become longer to process. Leakage
Check the tutorial by Steven Smith about overlap-add method and FFT convolution - you don't need a very big FFT, you can process in real time.
Hi, 1.For Worst Case Analysis,We are giving Less Voltage and Higher Temperature... For Best Case Analysis,We are giving High Voltage and Lower Temperature... But in both Cases We are giving Same process Value (P=1)... Can anybody tel me, a.Wat is process? b.Why we are not Changing the process value? 2.For Setup analy,W
Hi, Does anyone have any idea how much the dielectric constant of the insulator material changes in standard CMOS processes and how much better/worse this gets with process scaling? I guess the TC should increase as more focus is placed on low k for less parasitic capacitance?
CMOS process technologies are available from most foundries in these gate lengths : 0.18 ?m, 0.13 ?m, 90 nm, 65 nm, 45 nm etc. What factor determines the scaling from one technolgy to another ? One trend i notice is that there is divide by 2 scaling in every alternate generations , ie, 0.18 /2 is 90 nm, 90nm/2 = 45nm, 0.13/2 is 65 nm (...)
hi, I have a question on the relatioonship between the noise characteristcs and the cmos process scaling. I intend to design a TIA(155M) and 0.6um and 0.35um mixed cmos process are availble. I just want to know, from the view of noise improvement, which process is better? Scaled process means better or (...)
I don't know exactly you want to know. But in general, when the design scales from other process, lots of parameter should be consider. Such as Vt, gate capacitance, not only the voltage and length.
