  1. 1. Design of Ultra-Low-Power Analog-to-Digital Converters

    Author : Dai Zhang; Atila Alvandpour; Trond Ytterdal; Linköpings universitet; []
    Keywords : analog-to-digital converter; ADC; successive approximation register; SAR; SAR ADC; ultra-low-power; power consumption bounds; medical implant devices;

    Abstract : Power consumption is one of the main design constraints in today’s integrated circuits. For systems powered by small non-rechargeable batteries over their entire lifetime, such as medical implant devices, ultra-low power consumption is paramount. READ MORE

  2. 2. High-Speed Analog-to-Digital Converters in CMOS

    Author : Siyu Tan; Integrerade elektroniksystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; A D converters; CMOS circuit design; ΔΣ ADC; high-speed ADC; Nyquist-rate ADC; oversampled ADC; SAR ADC; 5G;

    Abstract : The Analog to Digital (A/D) Converters (ADC) are vital components in high-performance radio devices. In the receiver end, the signal received by the analog front-end can not be directly analyzed by the digital core, thus requiring high-performance ADC circuits acting as bridges connecting the analog and digital domain.

    Abstract : Silicon carbide (SiC) integrated circuits (ICs) can enable the emergence of robust and reliable systems, including data acquisition and on-site control for extreme environments with high temperature and high radiation such as deep earth drilling, space and aviation, electric and hybrid vehicles, and combustion engines. In particular, SiC ICs provide significant benefit by reducing power dissipation and leakage current at temperatures above 300 °C compared to the Si counterpart. READ MORE

  4. 4. CMOS Data Converters for Closed-Loop mmWave Transmitters

    Author : Victor Åberg; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; SAR ADC; IQ-modulator; Data converter; mmWave; RF-DAC;

    Abstract : With the increased amount of data consumed in mobile communication systems, new solutions for the infrastructure are needed. Massive multiple input multiple output (MIMO) is seen as a key enabler for providing this increased capacity. With the use of a large number of transmitters, the cost of each transmitter must be low.

  5. 5. Continuous-Time Delta-Sigma Modulators for Ultra-Low-Power Radios

    Author : Dejan Radjen; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Delta-Sigma; continuous-time; analog-to-digital; ultra-low-power; clock jitter; single operational amplifier; SAR quantizer;

    Abstract : The modern small devices of today require cheap low power radio frequency (RF) transceivers that can provide reliable connectivity at all times. In an RF transceiver, the analog-to-digital converter (ADC) is one of the most important parts and it is also one of the main power consumers. READ MORE
