Abstract
This paper presents a power efficient 12-bit SAR ADC operated at a supply voltage of 0.6V. A binary-scaled redundant technology for SAR ADC is proposed based on split-capacitor DAC architecture. It suppresses the decision error without sacrificing the resolution. In addition, a feedback controlled bias technique is applied to the comparator reducing the power consumption for comparison by 21.6%. The proposed ADC was fabricated in 0.18µm CMOS technology. The measured DNL and INL is +0.46/-0.50 LSB and +0.98/-0.95 LSB, respectively. A SINAD of 68.1dB and SFDR of 83.0dB are achieved, respectively, while operating at a sampling rate of 100kS/s.
