ADC Design Technique

You are designing an ADC chip? OR designing a circuit card around an ADC for optimal performance?

thank u for your time. In fact an optimization by all means i need.i want chip designing techniques and also processing of signal outside adc for optimal performance.

I'm afraid I would need much more information to know where to start answering this question. The following may read as negative, but it is intended to be helpful (honest)

Do you have an idea what sort of ADC you would need - successive approximation, linear slope, flash, sigma-delta, hybrid..? What is the technical requirement - speed, resolution, monotonicity, absolute accuracy? What are your die constraints - technology, area? Are there electrical environmental issues - interference from digital signals, analogue coupling? Are you looking for a wide operating range?

Some of this has much in common with DACs - have you looked at previous posts on that topic?

Returning to ADCs, have you read the Wikipedia article
http://en.wikipedia.org/wiki/Analog-to-digital_converter
and followed its references? Have you looked at application notes from commercial ADC suppliers (Philips, NatSemi ...)?

Once you have this, you should be in a position to ask detailed questions.
