## Error in LTspice simulation

Hi, i am trying to simulate the attached .sp file in ltspice to analyse the static noise margin of sram cell. but it is showing some errors. Can anyone please help me to resolve it.

## SRAM simulation in LTspice

hi, how to do static noise margin analysis of 6t sram cell in LTspice.

## Static noise margin measurement of SRAM in LTspice

hi, I am doing the simulation of 6T sram cell in LTSpice. I want to measure the SNM of the cell. How can i do it in LTspice. Please suggest me a solution

## How to know if there is noise affecting my signal

0 down vote favorite I have a signal shown in the attached figure and the fft of that signal as well. In addition I have also attached the fft of the static noise signal. You can see that in the original signal there are harmonics present specially on the first half of the curve. I really dont expect them coz in my experimental setup i try to el

## SRAM static noise margin (SNM) hold and read

Hi all, i'm doing the simulation and measurement on the SRAM SNM (hold) and SNM (read) All the papers and textbooks say SNM (hold) are supposed to be much larger than SNM (read), but my simulation result shows they're quite close, e.g. 226mV and 223mV. anything wrong? or is it possible they can be that close? 65nm cell size 120/160/240, one m

## Ground Loop Problems

In some cases the purpose is to prevent static buildup. Or it may be to reduce mains hum and/or EM noise.

## [Moved] Static Noise Margin Simulation for Ternary SRAM

Hello, I am trying to simulate Ternary SRAM cell. which can memorize logic 0,1,2 or in vtg level as 0v,1.5v,3v. I want to find simulation result for SNM of the ternary SRAM. Please help. 117540 SRAM cell SCHEMATIC Thanks in advance. regards, Siddharth

## [Moved] Suitable Processor for Automotive Applications

Vehicles can develop static charge. For instance, moving through air at high speed. Engines create ignition noise. This can travel in the wiring, or it can be broadcast as EMI. Hot and cold extremes. Possible exposure to sunlight and UV rays. Possible exposure to engine fluids. Battery voltage drops when starting engine (8 or 9V is typical). V

## PSS & Pnoise simulation for sample and hold circuit

Accoring to kT/C noise theory, I expect to noise power as much as 37.692nV2/Hz because of 100fF load capacitance. However, the simulation results shows just 0.3464fV2/Hz at flat zone (white noise by thermal) likeIntegrate regarding frequency. Then you can get same value for both static case(dc-noise) and (...)

## Analog multiplexer issue

- phase noise on the edge of a static sensor is normal. - the quadrature noise should not exceed +/-45deg , so only 1 line should have noise. A state machine should ignore the commutation noise on one channel if you execute this properly in a PLL state machine. Start with a State machine filter that (...)

## SNM Simulation for 6T-SRAM cell

Hi, Can anybody tell how to plot SNM for 6T SRAM cell graphically using matlab.I have obtained butterfly curves ?I am working on the following paper"static-noise Margin Analysis of MOS SRAM Cells EVERT SEEVINCK, SENIOR MEMBER, IEEE, FRANS J. LIST, AND JAN LOHSTROH, MEMBER, IEEE".Although there is a method provided in the paper but complete informa

## static displine in digital abtraction

HI,, evry 1 can any one share me the link wer i get cmplt info abt static discipline info.... noise margin ad noise imunity

## static noise margin in digital circuits....???

can any one explain how to draw a buffer grap using VIH=3.5v,VIL=1.5,vol=0.5,voh=4.4 noise margin......

## Do op amp low pass filters stop changes in DC voltages?

Couple of thoughts on touching live circuits: 1. Your body can have a static charge of electrons big enough to ruin electronics. Great rule of thumb is to keep your fat thumbs off sensitive electronics. 2. If you hold onto the line you are either acting like an antenna for the ambient power EMI and other signals directly into your circuit or a g

## What is a Square transistor ?

Hi, Can anybody tell me what is a square transistor.I came across this word when I was reading the following paper:"static-noise Margin Analysis of MOS SRAM Cells EVERT SEEVINCK, SENIOR MEMBER, IEEE, FRANS J. LIST, AND JAN LOHSTROH, MEMBER, IEEE".

## MEMS-Accelerometer and instrumentational amplifier

Hello. I'm trying to build a mems accelerometer that can sense very small vibrationers at the milli g (g=9,82m/s^2) level. (It equals to a really low output voltage fyi) So I have checked out this device at Analog Devices ADXL203 the vibrations are

## Sram Static Noise Margin Question

I have attached Butterfly diagram of cross coupled inverters In the figure i have considered two noise sources one which is less than Vdd/2 and another greater than Vdd/2 1. In first case because of the positive feedback the output still remains the same. 2. In second case since Vn2>vdd/2 there fore due to positive feedback the state is flipp

## how would i make a 1/2 second delay on a button

You want to shunt the internal switches of the PS3 using the internal power source to avoid noise, but if you are not careful with static, you can damage the device. so you want the L1 to react immediately to external SW1 but R1 to react after 0.25 ~ 0.5Sec.? What about release time? Are the internal switches NO or NC? What voltage is avail inside

## FPGA input buffer current consumption

noise may play a role, but static current consumption of a CMOS buffer with intermediate input voltage is sufficient to explain the effect.

## Noise reduction in voip (skype)

The idea I have is (all static now, but for an application later) take a sample of a person talking for about 3 seconds. Then a sample of the person not talking for also about 3 seconds. Then, subtract the current stream of voice (I hope you get what i mean) with the sample of noise that is recorded.. Is this a good idea to try?[
