Abstract— A time-interleaved flash-SAR ADC architecture has been suggested for high speed A/D conversion. Owing to the MSBs determined by the front end flash ADC, SAR ADC completes the A/D conversion in a reduced number of cycles. Time-interleaved SAR ADCs with a commonly shared low resolution flash ADC provide a new size and power efficient

architecture [7]-[9] allows pipeline ADCs to achieve record efficiency. A SAR assisted pipeline ADC (Fig. 3) is a two-stage pipeline that uses the SAR architecture to implement the both the first and second stage sub-ADCs. Compared to a conventional pipeline ADC, this allows a higher first stage resolution, thereby improving linearity

2020-11-01 · The proposed architecture is based on a traditional charge-redistribution SAR ADC , suitably modified to hold different signal samples at the same time. Both the original SAR and the proposed modifications are illustrated in Fig. 5. Download : Download high-res image (707KB) Download : Download full-size image; Fig. 5.

Second, the calibration is intrinsically performed at the right input common mode voltage. After convergence, all LSB comparators would have the same offset as the reference comparator, which sets the entire ADC offset.

An ultra-low-power area-efficient 8-bit successive approximation register (SAR) analog-to-digital converter (ADC) is presented. To achieve ultra-low-power performance a DAC architecture is proposed that employs two rail-to-rail low-power unity-gain buffers and only 4 minimum-size capacitors instead of the conventional binary-weighted capacitor array.

Fig.2 illustrates the case for N = 4. 3. Proposed SAR ADC Architecture We propose using an SAR ADC that has three comparators (or, equivalently, a 2-bit flash ADC) and a DAC with three reference voltage outputs (Fig.3). A SAR ADC architecture. In order to improve the common mode noise suppression capability and conversion accuracy, the AD converter usually uses a differential structure. Capacitor DAC circuit • Redundant pipelined SAR ADC is a strong candidate to meet the stringent requirements for ATLAS LAr upgrade • Split-ADC architecture with SEE detection techniques provides a potential (architecture + analog) solution to SEE • Various SEE-protection techniques and proven TID-tolerance will The pipelined analog-to-digital converter (ADC) has become the most popular ADC architecture for sampling rates from a few megasamples per second (Msps) up to 100Msps+. Resolutions range from eight bits at the faster sample rates up to 16 bits at the lower rates.
