Hello everyone,
I need some help in designing a DAC. To my understading aftre going through I drew this block diagram(attachement).
They are few questions I couldn't able to sort it out
1. How to decide the resolution of DAC?
2. I am thinking of using split array charge scaling architecture. Is it going to be better option considering layout area and Speed and accuracy?
3. Is resolution related to frequency?(Max of 50Mhz can be used in designing)
4. Do I need some additional circuitary in the block diagram?
Specs: vdd:1.8V,Vout min≥200mv;Vout max ≤1.6
Please let guide me.
Thank you.
