Also, election of the m and l bits of MSB and LSB capacitors banks, respectively, is studied to reduce SAR errors.To exemplify and quantify the non-idealities, MOM capacitors are used. In particular, MOM layout parasitics and effective capacitor’s value is obtained with an electrical extraction tool using a flattened view of the MOM. Effects of capacitors layout placement in the SAR and their surroundings in the effective capacitance value are quantified. A quantitative study of a 10-bit un-even split-capacitor SAR is done for different combinations of m and l bits. Finally, a qualitative set of guidelines to choose the distribution of these bits is listed. |
