IEEE CASS Rio de Janeiro Chapter

CASS Distinguished Lecturer Sameer Sonkusale Abstract   This talk will explore the new realm of making flexible sensors and diagnostics for point of care diagnostics. Specific applications range from early screening in resource poor settings, to smart wound dressings for chronic wounds. The key contributions of the work are on utilization of locally sourced universally available, low-cost materials such as paper, threads and textile, and close integration of such devices with  miniaturized and integrated circuits and systems. In the first part of the talk, I will focus on the development of sensors and diagnostics on paper as an unconventional substrate. Fabrication of these devices rely on low cost, room temperature processing using a combination of screen and wax printing using locally available materials. Readout is achieved using a CMOS based low power cell phone accessory for point of care diagnostics. Other versions include using the imager on the smart phone itself for readout. An application in monitoring saliva for stomach ulcer screening will be discussed for paper diagnostics, In the second part of the talk, I will discuss our work on thread as an unconventional substrate for the realization of microfluidics, sensors and electronics for diagnostics. Beyond serving as an ideal platform for disposable lab on chip applications, thread also serves as an ideal platform for wearable and implantable application where softness, flexibility and the possibility of an intimate interface with skin and tissue is important. Application in chronic wound monitoring, smart surgical sutures and sweat monitoring will be shown. The talk will be interspersed with knowledge gaps and how the biomedical circuits and systems community can help address those in near term and long term.

A general characteristic for the transistors of a given length in a given process is obtained. Therefore, it gives a global view and orientation about the design space. This makes it very suitable for helping the designer to gain insight on how to tune the design and, particularly, aiding novel designers to quickly find their way in the analog design art. The same applies to the, somehow “dual”, inversion coefficient (IC) based methods. Both methods are based on magnitudes (gm/ID and IC) that are ratios (or proportional to ratios) of key magnitudes of the transistor operation. Extensions and evolutions of the gm/ID method have, implicitly or explicitly, identified this “ratio based characteristic” and have shown the advantages of considering other key ratios of magnitudes that share the same characteristics as gm/ID of being W independent. The approach presented is particularly appropriate for nanoscale devices where multiple unitary devices in parallel are usually applied.  This talk will provide an overview on these ratio based analog design approaches, contributing to show a general vision about them. These methods originally targeted small signal analog design. In the talk it will be shown examples of extension of the basic idea to nonlinear RF blocks (power amplifiers and envelope detectors) as well as to distortion analysis.

It will be presented some highlights of the reverse engineering of the Z8000, which control part was designed by hand, showing several layout optimization strategies as well an optimization of the number of transistors. The observation of the Z8000 layout inspired the research of methods to do the automatic generation of the layout of any transistor network, allowing to reduce the number of transistors to implement a circuit, and by consequence, the leakage power consumption. Power Optimization is a keyword in the IoT world. Some of the layout automation tools developed by our group are briefly presented. It will also be presented why the use of visualization tools can help to improve the quality of EDA tools and to improve the quality of the solution.

There is a “tree of technology” too. In truth, there are many; among the most notable are CMOS, and xPU. In these “trees of technology”, each new generation inherits the parental “genes”, unchanged, unchallenged, just smaller (CMOS) or bigger (xPU), an artificial Galapagos Islands ecosystem. Darwin’s “tree of life” has been challenged by UIUC Prof. Carl Woese, an “evolutionary biologist”, who proposed a more “tangled tree of life”, in which gene transfer, and therefore evolution happens both vertically (VGT), slowly, generation after generation of one organism, and horizontally (HGT), rapidly, across different organisms. Over the last four billion years, there have been several bursts of horizontal evolution, among which the “Cambrian explosion”, when practically all major phyla started appearing in the fossil record. In this talk, I propose that we are at the dawn of a technological “Cambrian explosion”; that we must challenge the established “trees of technology”; that only the entanglement of many different “trees of technology” will allow us to leapfrog the fundamental, physical limits that CMOS and xPU, are hitting against.

Title Humans and Semiconductors Interface: Energy Efficiency and Edge Artificial Intelligence Abstract Humans' and Semiconductors' relationship have reshaped history for the past five decades. From Moore's Law, the semiconductor industry has favored a fast and low-cost development of technology. During the crisis, supply chain ruptures and resource scarcity have changed such equilibrium. It is time for the microelectronic research field to bring out some paradigms breakthroughs in terms of extreme energy efficient systems and bringing artificial intelligence to the sensor's edge. This tutorial summarizes the state of the art in this field and brings some recent scientific results of our team. Few of them includes: (a) low area, low power eNeurons suitable for Spiking Neural Networks; (b) spiking frequency modulation over audio bandwidth suggesting a Smart IoT hearing; (c) spiking frequency responsiveness over input waves suggesting a Smart IoT vision; (d) deep learning and energy efficiency trade-offs in analog spiking neurons.
