High performance data converters; Rethink analog IC designNan Sun, Muhammed Bolatkale
Nan Sun: Rethink Analog IC DesignI will present several unconventional data conversion architectures. First, I will talk about how we can make use of noise, which is usually deemed as an undesirable thing, to estimate the conversion residue and increase the SNR of a SAR ADC. It is an interesting example of stochastic resonance, in which the presence of noise can lead to not SNR degradation but SNR enhancement. Second, I will talk about how we can perform data conversion below the Nyquist rate by exploiting the sparsity of the input signal. I will show two example compressive sensing ADCs and how the effective ADC conversion rate can be reduced by 4 times but without losing information. Third, I will show how we can prevent the seemingly inevitable kT/C noise in a Nyquist-rate pipelined ADC by using a continuous-time SAR based 1st-stage. This can substantially reduce the requirement on the ADC input capacitance, greatly reducing the ADC driver power and reference buffer power
Biography of Nan SunNan Sun is Associate Professor at the University of Texas at Austin. He received the B.S. from Tsinghua in 2006 and Ph.D. degree from Harvard in 2010. Dr. Sun received the NSF Career Award in 2013. He serves on the Technical Program Committee of the IEEE Custom Integrated Circuits Conference and the IEEE Asian Solid-State Circuit Conference. He is an Associate Editor of the IEEE Transactions on Circuits and Systems – I: Regular Papers, and a Guest Editor of the IEEE Journal of Solid-State Circuits. He also serves as IEEE Circuits-and-Systems Society Distinguished Lecturer from 2019 to 2020.
Muhammed Bolatkale: High Performance Data ConvertersA next generation automotive radio receiver, an all-digital Class-D amplifier, and an advanced Bluetooth transceiver have one thing in common: they rely on high-performance data converter architectures to enable best in class performance. This talk will give an overview of GHz-sampling data converters, especially focusing on wideband delta-sigma and hybrid data converter architectures. We will touch upon state-of-the-art systems and circuit level designs fabricated in advance CMOS nodes.
Bio Muhammed BolatkaleMuhammed Bolatkale is Senior Principle Scientist at NXP Semiconductors and part-time Associate Professor in the Electronics Instrumentation Laboratory at Delft University of Technology.
