Design of 10-bit 10MS/s Time-Interleaved Flash-SAR ADC Using Sharable MDAC

This paper presents a 10-bit 10 MS/s Time-Interleaved Flash-SAR ADC with a shared Multiplying DAC. Using shared MDAC, the total capacitance in the SAR ADC decreased by 93.75%. The proposed ADC consumed 2.28mW under a 1.2V supply and achieved 9.679 bit ENOB performance. The ADC was implemented in 0.13μm CMOS technology. The chip area was 760 × 280 μ㎡.
