pipeline adc calibration

Hi guys...
we were jsut discussing calibration in our team....
can anyone tell me how one calculates the calibration parameters
in a 1.5 bit/stage pipelined ADC

Thx

adc calibration

well..the problem is ...i dont know how to do it.... :? ...
...tell me one thing.....u hav the following situation :
I need a schematic to contains :-
1. symbols form analog lib
2. functional lib
3. models o/p by model gen
....how do this...and importantly...what is the simulator that u will choose
in simulation setup..

Thx,

site:www.edaboard.com pipeline adc calibration

there many kinds of calibration schemes for 1.5b/stage pipelined ADC!
if you want schematics, I am afraid there are not much on web!

some IEEE papers may be helpful:
"Digital_Domain Calibration of Multistep Analog-to-Digital Converters"
"Background Digital Calibration Techniques for Pipelined ADC's"
and so force

pipelined calibrated model

I am looking for Digital Calibration technique for pipelined 1.5bits/stage A/D converter .Trip points in A/D are Vref/4 & -Vref/4 and decision points to each stage are 00,01 and 10 respectively based on the region where the Analog residue falls into .MADC is a differential Architecture .

I would like to find Calibration Coefficients for Negative/Positive input & Coefficient for the offset too. I would like to know the following

1)If the differential input has to be sampled with respect to the ground Voltage or +/-Vref/4 ??
2)Do I have to find capacitor mismatch in each stage ??
3)Can I use the same ADC to find the error code ??

thx,

adc callibration

Here is transfer function of 1.5bit pipelined A/D.
Vout=2*Vin+D*Vref ->D=1 ,Vin<-Vref/4
->D=0 ,otherwise
->D=-1,Vin>Vref/4

you dont have to calibrate capacitor mismatch of each stage, just do calibration on MSB of ADC. You can get more details from acticles I have referred upward!

rsd 1.5bits/stage algorithm

I think we have to have a backend pipelined ADC for digital calibration or use the same to compute the calibration coefficients .

analog calibration pipeline adc

you may search topic "1.5bit | adc" in IEEE Xplore, then you may find related papers. The thesis is too long.

You can refer to this IEEE paper(2001):

behavioral model of pipelined adc

I also need info for ADC calibration. As per I know this is the techique to calculate the
error coefficients of 1st few stages with some algorithm.

I also want to know the hardware implementation of this
