Researcher – Broadband analog integrated circuits for next-generation optical transceivers

Research & development - Gent | More than two weeks ago

The Design group of IDLab, Ghent University and imec is seeking a postdoctoral researcher to join its newly established High-Speed and Coherent Transceiver Research Programs. The researcher's technical and scientific responsibilities covers analog electronic integrated circuit design ranging from individual blocks to fully functional chips. The focus is in particular on broadband circuits designed using high-performance processes such as SiGe BiCMOS to ensure outstanding analog performance, which can be bandwidth, low-noise, high linearity or a combination of these.

Researcher – Broadband analog integrated circuits for next-generation optical transceivers

What you will do

The Design group has over the past decade realized a large portfolio of broadband integrated circuits such as modulator or laser drivers, transimpedance amplifiers, ultra-high-speed analog multiplexers, equalizers etc. Typically, these devices are implemented using the most advanced SiGe BiCMOS processes to achieve high drive voltages, low-noise operation or linearity. The group wishes to further extend this portfolio both in terms of performance (e.g. targeting 50Gbaud and even well beyond 100Gbaud) and functionality (e.g. burst-mode capability, accurate automatic gain and offset control for linear front-ends, non-linear functions). The group is therefore seeking a postdoctoral researcher with following responsibilities:

  • Development, realization and test of analog integrated circuits typically implemented using SiGe BiCMOS processes, including but not limited to for example:
    • Broadband linear lasers or modulator drivers, including automatic bias and gain control functionality,
    • Broadband linear transimpedance and variable gain amplifiers, including (burst-mode) automatic gain and offset control,
    • High-speed analog (de-)multiplexing circuitry, equalizers,  
    • Supporting circuitry such as operational amplifiers, voltage or current references where needs arise. 
  • Perform or support the measurements required to evaluate the performance of the fabricated integrated circuits. If required this may include the realization of required supporting material such as high-speed capable printed circuit boards, ceramic, interposers etc.

What we do for you

The successful candidate will join an internationally renowned team of high-speed electronic integrated circuit designers. He or she will get the opportunity to realize and shape the Design group’s roadmaps towards next-generation optical transceivers with >100Gbaud symbol rates. The successful candidate will be provided every opportunity to publish the outcomes of their research work at high-impact international conferences and leading journals, both in the area of IC design as well as optical fiber conferences.
This position is available for a definite duration of two years initially, and can be extended pending funding applications.

Who you are

  • A PhD degree in Electrical Engineering or equivalent with a strong background in realization of high-performance and high-speed analog and mixed-signal integrated circuits,
  • Proven track record of successfully tested integrated circuits such as broadband amplifiers, equalizers, multiplexers etc, preferably using SiGe BiCMOS processes.
  • Proficiency with design tools such as Cadence, Mentor Graphics, electromagnetic simulators, parasitic extraction and verification tools is a must,
  • Experience with advanced measurement equipment such as high-speed real-time or sampling oscilloscopes, vector network analyzers, spectrum analyzers, pattern generators or error detectors,
  • You integrate well into a multi-cultured and diverse team, and are a teamplayer,
  • You are allowed to work in Belgium.
