Associate Professor
Zeljko Ignjatovic is an Associate Professor in the Department of Electrical and Computer Engineering at the Hajim School of Engineering & Applied Sciences, University of Rochester. He holds a PhD in Electrical and Computer Engineering from the University of Rochester (2004). His expertise includes analog VLSI design, high dynamic-range Sigma-delta converters, and ultra-low power sensor interfaces. Education: PhD in ECE, University of Rochester (2004). Research focuses on advancing analog and digital signal processing circuits. Key areas include: High-precision Sigma-delta A/D converters Fully-digital image sensors with pixel-level conversion Focal plane compression reducing computational demands Audio signal data hiding techniques Notable contributions include a 100-fold improvement in dynamic range and 50-fold power reduction in CMOS image sensors through Sigma-delta pixel architectures. Ongoing work explores further optimization of low-power sensor interfaces and compression methodologies. No scientific awards or grants are explicitly listed in the provided text.
