Do you want to specialize and deepen in Integrated Circuits and mixed-signal design? Are you eager to electronically control light, like none before? Do you want to influence the next generation of LiDARs (Light Detection and Ranging) devices and integrated-circuits? Do you want to closely collaborate with scientists from Belgium, the Netherlands, France and Denmark?
This exceptional opportunity presents a chance for us to explore the realm of massively integrating Digital-to-Analog converters onto a single chip, thereby generating control signals for photonic beamformers designed for FMCW LiDAR devices. In the course of this research, we may draw upon concepts from various fields, including phased arrays, digital Sigma-Delta (ΣΔ) modulation, digital signal processing (DSP), and power-efficient IC design. It's worth noting that this research project forms a crucial part of a collaborative initiative within a pan-European research network. We want to use the results of this research, together with our partners, to create innovative demonstrators for the next generation of LiDARs.
In this role, you will fuse your passion for analog and mixed-signal IC design with the latest advancements in data converters, sigma-delta and pulse-width modulation (PWM) techniques, as well as analog IC design. The fruits of your labor could potentially pave the way for breakthroughs in other applications that demand large arrays of data converters, such as wireless communication, UWB ranging and automotive radar.Eindhoven University of Technology (TU/e)

You will be responsible for researching, developing and implementing key architectural and circuits related aspects for creating an array of unit Digital-to-Analog Converters interfaced to hundreds of optical phase shifters. The main goals of the research project include: a) developing an area efficient Digital-to-Analog Converter (DAC) unit to drive optical phase shifters; b) exploring the limits of DAC unit integration in a single IC; c) developing an ultra large IC array of numerous DAC units; d) interfacing the ultra large array of DAC units to optical phase-shifters.
Thus, we actively search now for suitable candidates, who are eager to assume responsibilities for answering key research questions, from an IC perspective, like:
- What will be an optimal architecture for a high-density array of DACs integrated on a single CMOS chip?
- How can we optimally use the array redundancy to improve efficiency of costs, like needed IC and power consumption? How can we use the properties of the application to improved the efficiency of our circuits?
- What are the limits for co-integrating data converters?
- How can we measure and characterize structures with massive flow of information?
The PhD research needs to be concluded in 4 years. A possible work plan with milestones can be:
- Year 1: Secondments in partners to study the challenges of co-integrating photonic with electronic ICs; co-design of the optical phase-shifting and DAC elements for optimal integration in commercial CMOS technologies together with our partners from Denmark.
- Year 2: design and fabrication of an IC test chip featuring a novel array of DAC units.
- Year 3-4: Design and fabrication of test Printed-Circuit-Board (PCB) to characterize the novel array of DAC units; Measurements for LiDAR beamforming.
- Year 4: PhD thesis and defense.
