The Lecture is:
Low-Power, Moderate-to-High Speed ADCs in Advanced CMOS Technology Nodes
Abstract:
The pipeline analog-to-digital converter (ADC) has long been recognized as the most suitable architecture for applications that require a balanced trade-off between speed, dynamic resolution (ENOB), energy efficiency, and silicon area. This makes them the preferred choice in demanding application domains such as Automotive (ADAS Radar and Sensor-Fusion), Space (Instruments and Telemetry), 5G/6G communications and SERDES interfaces, where high performance must coexist with stringent power and cost (die area) constraints.
In this webinar, we will discuss recent advances in low-power design techniques that enable moderate-to-high conversion-rates and moderate-to-high resolution ADCs in advanced CMOS technology nodes. The presentation will address three key aspects of modern implementations such as: (1) wideband analog frontends (AFEs) necessary to drive the ADCs; (2) innovative stage quantizer architectures; and (3) energy-efficient and ultra-fast residue amplification strategies.
By combining these circuit- and architecture-level innovations, next-generation pipeline ADCs can achieve excellent levels of energy efficiency, paving the way for their deployment in advanced electronic systems across multiple industries.
Biography:
Prof. João Goes (Senior Member, IEEE) received the bachelor’s degree in electrical and computer engineering (ECE) from Instituto Superior Técnico, Lisbon, in 1992, the M. Sc. and Ph.D. degrees from the University of Lisbon, in 1996 and 2000, respectively, and the Habilitation degree in electronics from the NOVA University of Lisbon (NOVA), in 2012. Since 1998, he has been with the Department of Electrical and Computer Engineering, School of Sciences and Technology (FCT), at NOVA, where he is a Full Professor, since 2017. Since 2023, he has been the Executive Director of UNINOVA Institute. He has been elected the General Council of NOVA, the top governing body of the University, from 2022 to 2026 (comprising only 14 faculty members).
In 2003, he co-founded and served as the CTO of ACACIA Semiconductor SA, a Portuguese engineering company specializing in high-performance analog frontend products (now RENESAS).
He supervised (concluded) 20 PhD students and over 80 MSc Theses. He has published over 250 papers in international journals and IEEE leading conferences (ISSCC, VLSI, CICC, and ESSERC). He was Associate Editor (AE) of IEEE TCAS—II: EXPRESS BRIEFS, from 2016 to 2023. Since 2024, he is currently an AE of IEEE TCAS—I: REGULAR PAPERS. He has been co-awarded as the Best AE of IEEE TCAS—I in 2024.
