The analog to digital converters is the key components in modern electronic systems. As the digital signal processing industry grows the ADC design becomes more and more challenging for researchers. In these days an ADC becomes a part of the system on chip instead of standalone circuit for data converters. This increases the requirements on ADC design concerning for example speed, power, area, ...

This work is a contribution to a drastic change in standard signal processing chains: Analog-to-Digital Converters (ADCs), digital processing circuits, Digital-to-Analog Converters (DACs)… Integrated Smart Devices and Communicating Objects are the important applications targeted by this study. The main objective is to reduce their power consumption by one or two orders of magnitude, by complete...

The authors present a low-power area-efficient subarray beamforming receiver (RX) structure for miniaturized 3-D ultrasound imaging system. Given that the delay-and-sum (DAS) and digitization functions consume most of area power in receiver, successive approximation register (SAR) analog-to-digital converter (ADC) shares its capacitive digital-to-analog (CDAC) with delay cells. As result, cells...

Successive-approximation-register (SAR) analog-to-digital converters (ADCs) represent the majority of the ADC market for mediumto high-resolution ADCs. SAR ADCs provide up to 5Msps sampling rates with resolutions from 8 to 18 bits. The SAR architecture allows for high-performance, low-power ADCs to be packaged in small form factors for today's demanding applications. This paper will explain how...

During the last decade, the development of the analog electronics has been dictated by the enormous growth of the wireless communications. Typical for the new communication standards has been an evolution towards higher data rates, which allows more services to be provided. Simultaneously, the boundary between analog and digital signal processing is moving closer to the antenna, thus aiming for...

This paper describes a digital-domain self-calibration technique for multi-stage analog-to-digital converter (ADC). An accurate calibration is achieved by using a modified radixbased calculation. The equivalent radix-based error term for each stage is extracted by measuring major carry jumps from the ADC transfer curve. A new multiplying digitalto-analog converter (MDAC) architecture using (ins...
