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.
