Hi,Berti, I don't know if i get offset due to charge-injection,but i really want to know charge-injection whether cause DC leakage!And i also agree with you,maybe, i have mistake when processing the bitstream.I have make the bitstream include 1 and -0.999,and i get similar result. In the process,i get the bitstream from 50.5u to 3327.3u,which inculdes 8192 points.the clock frequncy is 2.5MHz.however,i do fft in cadence get the same psd as in MATLAB.i have tride to simulate longger time,getting more point ,but got the same result!I am confused.cab you give some advice? regards!
