Sorry I cannot explain what is function.
However, here I have seen something extraordinary.
In this function along with many things I am also filtering the signal.
With one input if I filter the input then in the end I get equal XX and qip, if I dont filter it, qip is one sample more than xx...
in = input(0:t);
Ts = sampling time of input
processed_in = function(in); % here I have done some processing which reduces the number of samples
length of procesed_in is 'tn'
xx = 0:Ts:tn(end); %xx = start:interval:end;
yip = interp1(tn,decimated,xx); % Reconstruct using...
I have defined xq to be of same time period and length as the initial signal.
Therefore I expect the reconstructed signal to have exactly same no of points as the original but here I am getting 2 more points.
I have a signal whose length is 7500 samples.
I process this signal and which then downsamples and now the length is 1937.
Now I wanted to reconstruct this signal back to original, for this I used interpolation function in matlab interp1.
For comparing the reconstructed signal (for error) I...
I have been trying to set up remote simulation in cadence.
I have followed the steps told in the help manual.
1) Created a public key in the host machine.
2) I am able to perform rsh on remote host without login/password.
3) checked directory in the host, it has same file system path as...
Need help in understanding some things about noise and dynamic range analysis.
1) We know THD (total harmonic distortion) and THD+N (THD+Noise), which is THD measured with transient noise ON in cadence. Am I correct?
2) For a given input frequency and amplitude, SINAD is equal to THD + N...
I have made a simple transmission gate with one input (for signal with sinusiodal voltage input V0), a control (logic 0/1 to make switch On /OFF, with dc voltgae) and an output across a resistor.
I want to do the noise analysis of this circuit.
1) Since it is not a differential circuit, how can...
I am not able to understand this bulk connection.
How can I connect bulk to ground or supply>>
Do I need to use guard ring??
Thanks

I think I got the answer, I have to draw a via M1 to Pactive and M1 to Nwell each for NMOS and PMOS respectively, which will be connected to...
Thanks for your reply.
I have attached a snapshot of the layout.
As you can see the distance between nplus and pluse diffussion is less than 2um. But still I am getting these errors.
2. Maximum N+ Diffusion to nearest P+ pick-up spacing (inside P-Well or T-Well) is 20um
all nmos diffusion...
Hi
I am learning to use Cadence by designing an OTA.
I'm a bit stuck understanding what these error messages mean in the DRC checker.
if there is a link where I can find an explanation please let me know, otherwise I'd really appreciate some help understanding the following:

Re: Monte carlo analysis mean cutoff is double the fc from one point analysis in Cade
Today i rechecked everything.
Models are correct.
St. Dev is 11.23 for a sample for 100 no.
But BW mean with monte carlo is 81Hz, and with regular one point analysis is 52Hz.
However, I came to have an...
Re: Monte carlo analysis mean cutoff is double the fc from one point analysis in Cade
what do you mean by 'the parameter distributions for asymmetry'?
How can I check that?
Thanks for your help
Monte carlo analysis mean cutoff is double the fc from one point analysis in Cadence
I have designed a low pass filter in cadence with cutoff frequency 50Hz.
However when I do a monte carlo analysis it gives mean cutoff frequency as 80Hz.
How is this possible.??
All the parameters are same...
I have designed a low pass filter with OTA for very low cutoff.
However the filter comes out to have a very low dynamic range.
How may I can improve the dyanmic range of this OTA filter
One option could be increasing the size of capacitor, but it will increase the area of the filter.
Please help
