    PART 1
    I. Introduction
    - What we do at CERN (in general, Electrical Power Converter group, High Precision Measurements section)
    - The need for high precision + high dynamic range + stability
    - Unique challenges - environment, reliability, maintainability, etc. Differences between a metrology lab and accelererator tunnel. Measurements for closed-loop control and real-time applications
    -...

  3. 2. Multi slope A/D converters. Why the 50 years old technology is still (the only one?) relevant for the highest performance applications? (FEI STU)

    • The talk will explain historic developments of integrating ADCs, from single-slope, through multi-slope to charge balance multi-slope types.
    • Performance limitations of these ADCs will be explained, especially those relevant for metrological quality devices.
    • Some arrangements of multi-slope integrating ADCs do have an overlap with sigma-delta ADCs.
    • An outlook on ADC concepts other...

  5. 5. Voltage references, voltage standards and Josephson voltage standards (PTB)
    Dr Luis Palafox (PTB (Physikalisch-Technische Bundesanstalt))

    When a digitizer or an Analogue to Digital converter (ADC) is used to measure voltage, a fundamental contribution to the quality and stability of the measurement is the voltage reference used for that measurement.
    Semiconductor manufacturers specify ADCs as a “stand alone” component, but a high-resolution digitizer combines, or is limited by, the performance of the ADC and the voltage...

  7. 3. Towards a true 8-digit digitiser – EU Project overview and progress
    Dr Rado Lapuh (Left Right s.p.)
    19/02/2024, 17:00

    The True8DIGIT project addresses the development of a digitiser based on state-of-the-art analogue-to-digital converters (ADCs), operating from direct current (DC) to 100 kHz, meeting the demands for linearity, noise, and overall accuracy of high-level measurement applications that cannot be met using currently available digitisers.
    True8DIGIT project is framed as precursor to a more...
