How to use output codes of pipelined ADC to create input signal?

[ronanchang]

I have the output codes of the pipelined ADC,and how do I use these codes to create the input signal?? May I use the G-element??? Or someone has better ways to get the original signal??

Why don't use a higher resolution DAC to convert the signal?

Re: About pipelined ADC

Use a DAC that has higher resolution than your designed ADC. That's how ADC is characterized i the labs. Use DAC to recover your input signal and analyze it. Another way, is to use MATLAB or some other DSP program to look at your ADC output. Take a snapshot of the ADC output (small amount of data) and FFT it using MATLAB.

You can have a behavioural model of the DAC which can convert the inputs to an analog wave.
