RaM-SAR: A Low Energy and Area Overhead, 11.3fJ/conv.-step 12b 25MS/s Secure Random-Mapping SAR ADC with Power and EM Side-channel Attack Resilience

2022 IEEE Symposium on VLSI Technology and Circuits (VLSI Technology and Circuits), 2022
This paper presents RaM-SAR, a 12b 25MS/s 11.3fJ/conv.-step secure random-mapping SAR ADC with power and EM side-channel attack resilience. Each conversion is randomly mapped to one of the thousands of conversion sequences to randomize power supply ...

Passive reference-sharing SAR ADC

Microelectronics Journal, 2015
Charge-redistribution successive approximation register (SAR) analog-to-digital converters (ADCs) are widely used for their simple architecture, inherent low-power consumption and small footprint. Several techniques aiming to reduce the power consumption, to increase the speed, and to reduce the capacitance spread have been developed, such as splitting

Modified BER Test for SAR ADCs

2020 IEEE International Test Conference in Asia (ITC-Asia), 2020
This paper presents a new post-processing method to estimate the real bit error rate (BER) of successive approximation register (SAR) analog-to-digital converters (ADCs) based on the conventional test scheme. Conventional testing method acquires BER based on difference between two measured output codes, rather than between a measured output code and ...

Selectable starting bit SAR ADC

2015 IEEE International Symposium on Circuits and Systems (ISCAS), 2015
Prior work used least-significant bit first quantization (LSBFQ) to conserve switching energy and comparator bitcycles, but is limited to low activity signals. Furthermore, LSBFQ results in a large bitcycle range in the quantizer. A novel selectable starting bit quantizer (SSBQ) is proposed which starts quantization with neither the MSB nor the LSB ...

Ultra-Low Power SAR ADC Using Statistical Characteristics of Low-Activity Signals

IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2022
Low-activity signals, such as voice, electrocardiogram (ECG), and ultrasonic signals, in the Internet-of-Things applications have both posed unique challenges and offered special opportunities for modern analog-to-digital conversion.

ADC trends and impact on SAR ADC architecture and analysis

2015 IEEE Custom Integrated Circuits Conference (CICC), 2015
The performance of ADCs continues to improve with process scaling. For low to moderate resolutions, SAR ADCs deliver the best energy efficiency. Interleaved SAR converters have become popular for very high sampling speeds. The SAR assisted scheme has dramatically improved the energy efficiency of higher resolution pipeline ADCs.

Advanced SAR ADC Design

2015
Chapter 2 discussed the basics of the SAR ADCs and their components such as the CDAC or the comparator in detail. Based on these fundamentals, Chap. 3 will present current research topics in the field of SAR ADCs. Generally, the core circuitry of the new SAR ADC should operate from a significantly lower supply voltage compared to the input voltage ...
