DL Seng-Pan U Visits SSCS-Beijing on 6 May: Talks at IMETU, the Institute of Microelectronics of Tsinghua University, About IC Design Trends [Chapters]

Summary form only given, as follows. The evolving broadband wireless communication increasingly drives fast development on high-performance consumer portable smart and green gadgets with longer battery life, which leads to growing demands on ADCs with higher energy efficiency. SAR-type ADCs which take advantages of CMOS technology downscaling for their "highly digital" implementation have been dominating large segments of high-speed and energy efficient ADCs with efficiencies down to fJ!conversion step at 100MHz+ sampling rate. This talk provides firstly an overview of the state-of-the-art high energy efficient ADCs, and then present the trends of the ADCs through the energy, speed and noise Analysis for various architectures including SAR & Binary-Search, Multi-bit SAR, Flash SAR and Pipeline SAR. Some practical design considerations will be also addressed.
