adc pipeline +post correction
hello everyone:
i am designning a 14bit pipeline adc, I used simulink to maike pipeline model,
first stage is a 4bit MDAC(gain*8),output 5bit data; then eight stages (1.5bit)(output 16bit data);the last stage is a 3bit flash adc.
the middle 8 stages 1.5bit MDAC and the 3bit flash adc, i used the digital correction way, it was correction.
but i am confused how to deal with the relationship between the first stage (5bit data) and the second stage's MSB.
anyone can help me~
thx

sorry, 4bit MDAC gain is 8, output 5 bit data
