ECE Associate Professor Predrag Spasojevic is the recipient of a new Office of Naval Research (ONR) award for the research project entitled "Post-Correction Techniques for Linearization of Wideband Analog-to-Digital Converters." Professor Spasojevic is the Rutgers PI on a 2-year $1M collaborative effort with Expedition Technology Inc., with Rutgers share of the award being $300,000.
In this project, Professor Spasojevic will develop post-correction mechanisms for the non-linearities in wideband, low-resolution Analog-to-Digital Converters ( ADCs) to improve their signal to noise ratio (SNR) and spurious free dynamic range (SFDR). Wideband ADCs play a critical role in supporting high data rate low latency applications and the goal is to resolve inherent non-linearities in ADC design and manufacturing that create undesirable artifacts which reduce SNR and worsen the SFDR of the ADC. Wideband ADCs are particularly susceptible to the non-linearity effect, as they often have lower quantization resolution which makes these artifacts more prominent.
