you can input a ramp signal. ideal number is a code display times with ideal condition. active number is a code display times with active condition.
DNL(i)=(ideal number - actvie number)/ideal number
INL(i)=∑DNL(0:i)
Hi niket,
I am working on same design of TIQ flash ADC using mentor graphics tools.how did u find the speed of adc,can you please give me ur specifications ,how speed it is workin.
thaks a lot in advance.
Regards,
Raj
finding speed is simple as we can find the code trasition delay.......with respect to clock........generally sndr and snr falls and which defines the max inp frequency........stilll i have to check it
you can give a sin signal,then you can analyse the output datas with spice-explore:converte the output datas to digital signal,then converte the digital signal to analog signal,finaly u can get the sndr,snr,sfdr,enob,etc. you also can refer to the spice-explore help.
Hi, I got Spice simulation results for 6 bit TIQ ADC for sinusoidal input.But i could not get an idea to find INL,DNL,SNR,SNDR and EDOB.How to find all these in Matlab and how can i give spice outputs as input in Matlab.can you please explain for same in Detail.Thanks in adv.
