Hi Everyone, I have just designed a 8-bit folding interpolation adc. When I simulate my adc, I cannot get to 8-bit of resolution. The SNR that I got from the power spectrum is only -30dB. The noise level is at -40dB. Is there any technique I can use to lower the noise level in the adc. Can anyone who has experience with (...)
hi, I read the article that folding&interpolation adc facing frequency multiplication problem in adc processing. And S/H can eliminate this problem. Can anyone explain those ? Why frequency multiplicaiton happens ? and why S/H can eliminate it ? best
Bandpass sampling is best approach to have reduced power consumptation for the adc implementation. I think most adc implementation independend from the architecture (Flash, Folding, interpolation, Multistage-Subranging,..) come down to about 150-500fJ/decisionstep. So a 10bit/1GS/s have (2^10-1)*1e9Hz*150fJ=153.5mW These results (...)

Hi, I am trying to design an adc with 8bit 2GS/s specifications with minimum power consumption. The process is 0.13um BiCMOS. I am trying to look for papers and found some groups used folding+interpolation to achieve >1G with 8bits resolution. Is F+I the only possible way to achieve the specs or there are better ways to do it? Do anyone have some r
You are experiencing some "numerical noise" due to the interpolation between two simulation steps, i.e. your 2048 points do not always fall on one of the points calculated by the simulator. So, the 0.01ns simulation is probably the correct one.
hi i have a problem , i work with dspic30f2010 , i should convert an analog signal to digital so i use the adc of the dspic but after that i should treat the result of the conversion with a program of interpolation then transfer it with the can bus; my problem is that i read the datasheet, but i didn\'t find a solution , to do the program of inter
For high sampling rate in Gs/s of scope passing data to fpga ,interpolation will be used , for a 8 bit adc , multiple and sum in sinc interpolation will result in 16 bit data . 255 pixel of lcd is representing 8 bit data,but after interpolation 16 bit is comes out , how to put this 16 bit into 8 bit "heights" ?

I could't find a good and fast video adc for my project and I have to use my graphic card adc but I don't know how.if anybody knows how to use video adc on the video is not important which card it is.I can find most cards.
Look in . They have very fast adc. But is 12 bit. Mybe you can do beter res. with interpolation. Look app. notes on web site. Or try with Analog Devices audio AD converters. They are wery fast with hi resolution.
Can give me some articles or vhdl souce code about the interpolation Time Counter.I need it very urgently.THX.

Hi, I thought that you want to design ISP for CCD or CMOS image sensor. 2 line buffering can supports 3 line signals, and you can get enough image quality from them. Don't worry about serious problem. But interpolation will be suffer aliasing effects and image soomthing effects. interpolation is same effects with low pass filtering. So, you
