I have chosen a switching scheme for my 10-bit SAR ADC. But I am stuck at designing the sar logic control for DAC switch, comparator, S/H bootstrap switch. As shown in the picture is an example of 3-bit ADC. But my design is 10 bits and I need a synchronous SAR logic. I also review the knowledge of digital design for Moore, Mealy state machine, state table, stage assign,... that I learnt in undergraduate; however, the number of states here are so many while I have to design it in cmos and gate level in cadance. I also read many paper but they just show the circuit directly without explaining where it come from. Can you help me a straigtforward way to design it?
