Zeljko Ignjatovic

简介

Zeljko Ignjatovic received the PhD in ECE from the University of Rochester in 2004. He is currently an associate professor of electrical and computer engineering. He has specialized in the design and analysis of analog VLSI integrated circuits. His research spans high dynamic-range Sigma-delta A/D converters, ultra-low power sensor interface circuits, fully-digital image sensors based on Sigma-delta pixel level A/D conversion, focal plane compression in imaging applications, and data hiding in audio signals. He has developed several architectures that improve Sigma-delta A/D conversion, architectures by reducing their offset, 1/f noise, and harmonic distortions. He has also developed a variety of image sensors based on Sigma-delta conversion at the pixel site. These image sensor architectu
