Title: About inter symbol interference (ISI)
Post by caosl_zju on Feb 7^th, 2009, 9:09am

hi, all
I have a question confused me recently. We know that in sigma delta ADC or DAC, which implemented with current steering(feedback DAC in sigma delta ADC) elements. Many papers stated that the ISI will give rise to SNR and THD performace decrease, but why this is arose?
Thanks in advance.

Hi,

It is easier to get more help if you refer to one or more papers that supports the statement.
