ADC IC Architect

Job Title            Senior ADC IC Architect

Contract type Permanent contract

Starting Date Immediately

Location           Paris, Caen - France

Job function SCALINX is seeking a Senior ADC IC architect who will define and drive the design of high-speed high-performance wideband Analog to Digital Converter (ADC) functions to be integrated in our next RF SoC product dedicated to the 5G Communication market. In close collaboration with the analog/mixed-signal, digital and layout engineers and the silicon evaluation team, the candidate will be particularly involved in the architecture definition of the ADC including mixed-signal and/or fully  digital calibration techniques, the definition of the sub-blocks specification, the floorplan strategy and the test strategy.
The ADC IC architect will report to SCALINX CTO.

Work description

  • In close relation with the RF SoC architect, translate the customer requirement into an ADC specification (resolution, Noise Spectral Density, harmonic Distortion, SFDR).
  • Benchmark Time Interleaved ADC state of the art.
  • Define the ADC architecture and the calibration techniques to meet the dynamic specification with the lowest power consumption.
  • Work closely with the RF SoC architect and other designers to specify interface
    characteristic.
  • Define the specification of the AMS and digital sub-blocks of the ADC including
    calibration circuits.
  • Create high-level ADC behavioral model.
  • Discuss with the layout team floor planning and an isolation strategy to protect the
    sensitive analog/RF portions of the ADC against the noisy aggressors.
  • Contribute to the definition of a simulation strategy to validate the ADC performances
    and the calibration techniques with the rest of the ADC sub-blocks.
  • In close collaboration with the silicon evaluation team, contribute to the definition of
    integrated test points/pattern, the evaluation plan and production test strategy.
  • Participate to design reviews.
  • Participate to characterization.
  • Write documentation.

Qualification and Experience

  • MSc or PhD in Electrical Engineering or equivalent with at least 10 years of
    experience in designing and evaluating high-speed high-performance ADC functions.
  • Experience in specifying time-interleaved Analog-to-Digital Converters in advanced
    CMOS process is mandatory.
  • Experience in designing mixed-signal functions such as ADC and/or DAC is
    mandatory.
  • Deep understanding of error mechanisms that affect the linearity and noise
    performance of time-interleaved ADC.
  • Experience in definition and implementation of calibration techniques to compensate
    for the interleaving spurs in time-interleaved ADC architectures.
  • Experience in definition and implementation of calibration techniques to compensate
    for the static and dynamic errors of a single-channel Nyquist-Rate ADC such as
    Pipeline, Pipelined-SAR and SAR architectures.
  • Good understanding of digital and analog signal processing PRO/CONS to leverage
    the best of the two worlds.
  • Very good vision of the entire analog & mixed-signal IC design flow.
  • Strong leadership and communication skills to work with AMS, Digital and layout
    teams as well as the silicon evaluation team.
  • Experience with product development cycles from concept to production.
  • Team player with a critical attitude and sense of initiative.
  • Fluent communication in English (oral and written) is a mus
