Title: SAR ADC Layout Generation Using Digital Place-and-Route Tools

Language: English

Abstract—Digital place-and-route (DPR) tools are used to interconnect the analog macro-cells and digital circuits in two asynchronous successive approximation register (SAR) analog-to-digital converters (ADCs) with 12-bit 20-MS/s and 10-bit 100-MS/s. To realize the macro-cells of analog sub circuits, three techniques are used to mitigate the parasitic effects caused by the DPR tools. The software settings for the macro-cell generation are presented. Compared to the full custom method, to facilitate the interconnection wires of the 12-bit SAR ADC, it is speed up by a factor of 288 by using the
DPR flow.
