PhD Position (f/m/d) - Time-Interleaving Continuous-Time ADC

Research Project

Future generation automotive receivers for eg. FMCW MIMO radar reception require increasing larger bandwidths, higher dynamic range and spectral purity at low-power consumption. Conventional CT ADC architectures, such as continuous-time sigma-delta (SD), pipeline (CTP) and MASH sigma-delta modulators, face significant challenges in simultaneously achieving high DR, wide BW, and power efficiency. This project proposes the design and implementation of a time-interleaved continuous-time delta-sigma modulator (TI CT DSM) that leverages recent architectural innovations to overcome these limitations.

Objectives

Design of a time-interleaved CT DSM capable of multi-GS/s sampling rates and >400 MHz signal bandwidth with superior dynamic range, signal-to-noise-and-distortion ratio (SNDR), and power efficiency compared to state-of-the-art CTP and MASH ADCs.

Project Plan

• Phase 1: System architecture and behavioral modeling, define system specifications and performance targets

• Phase 2: Circuit design and simulation

• Phase 3: Layout, fabrication, and testing of prototype design

• Phase 4: Publication and benchmarking measured results with state-of-the-art CTP and MASH ADCs

Requirements for this role

• Master’s degree in electrical engineering or related field

• Strong background in analog/mixed-signal circuit design

• Background in data converters

• Experience in Cadence and Matlab

• 80 %-time commitment within a 3-year period, as this position is part time (80%) limited to 3 years
