MSc thesis project proposal
Broadband sigma-delta modulation (NXP)
Over the last two decades, the bandwidth of sigma-delta modulators has exceeded more than hundreds of MHz. The state-of-the-art sigma-modulators use combination of circuit techniques, advanced technology nodes and digital calibration to achieve wide bandwidth conversion. However, to achieve bandwidth greater than a few GHz, groundbreaking circuit design techniques must be developed. In this MSc thesis you will work on circuit techniques to increase the bandwidth of a sigma-delta modulator.In this master thesis project you will do/learn:
- In depth study of ADC (or DAC) architecture
- Design of analog and mixed-signal circuits in 28nm CMOS
- Circuit simulations with Spectre (or other simulator)
- Layout design of circuits and simulation of extracted layout
- Build understanding of impact of process imperfections and parasitic artifacts on performance
AssignmentOverview of the project planning (depending on the progress of the student):
- Literature review of the recent high-speed data converters.
- System level study of the proposed ADC architecture in Matlab/Cadence.
- Circuit and layout implementation.
- Tape-out of the IC followed by measurement.
- Process node: 28nm HPCP.
- Target tape-out date: Sep 2022
- Good knowledge of analog and mixed circuit design.
- Good understanding of Data Converters.
- Familiarity with Matlab and Cadence.
- You will be collaborating with researchers from NXP Semiconductors so good communication and presentation skills are essential.
