Could somebody explain me cleary how does this Digital error correction blks functioning ? Is tat it'll correct the gain & linearity errors in individual DAC n amplifiers ? Ur ans is very much welcome..thanx

Re: Digital Error Correction Function in 10 bit Pipeline ADC

Dear pnanda65675,

Digital error correction is mainly used to correct the comparator offset in pipelineADC, for example, for 8+1 stage (8 1.5b/stage stages + 1 2bit/stage) pipelineADC, there will be 18 digital code (8*2+2) output, through digital error correction these 18 digital code will be transfered to 10bit final code needed. A simple digital error correction includes several ripple adders.

As for up to 10-bit pipelineADC, digital error correction can't meet the request,
digital calibration (digital or analog) will be adopted. A digital calibration may include some ram, state machine and etc., a analog calibration may be realized through several capacitors, switchs and etc.

You can refer to IEEE papers for more detailed information.:D

Bg,
