SARADC怎麼著手

1） Digital Electronics, Bignell & Donovan, 4th Edition 这本书~~里面有 SARADC 完整的电路与操作说明~~.

2） comparator要有offset cancellation的, 可以用input/output offset cancellation的架構, 可以都用

4.关于EE247码密度测试INL和DNL的疑问

https://bbs.eetop.cn/thread-582622-1-1.html

最近在测试10bitSAR ADC的INL和DNL，芯片输入是正弦波，用的是EE247给的码密度matlab程序，但是程序中有一句T = -cos(pi*ch/sum(h));不太理解，望大神能指点一下。附：
datap=textread('4_1.txt','%s');
datan=textread('4_2.txt','%s');
datap=hex2dec(datap);
datan=hex2dec(datan);
y=datap-datan;
minbin=min(y);
maxbin=max(y);
% histogram
a=hist(y, minbin:maxbin);
h=a(1:2:end);
%h=h(2:end-1);
% cumulative histogram
ch = cumsum(h);
% transition levels found by:
T = -cos(pi*ch/sum(h));
% linearized histogram
hlin = T(2:end) - T(1:end-1);
% truncate at least first and last
% bin, more if input did not clip ADC
trunc=2;
hlin_trunc = hlin(1+trunc:end-trunc);
% calculate lsb size and dnl
lsb= sum(hlin_trunc) / (length(hlin_trunc));
dnl= [0 hlin_trunc/lsb-1];
misscodes = length(find(dnl<-0.99));
% calculate inl
inl= cumsum(dnl);
