    Description of the Talk

     

    This talk will cover practical challenges for cryogenic CMOS designs for next generation quantum computing. Starting from system level, it will detail the design considerations for a non-multiplexed, semi-autonomous, transmon qubit state controller (QSC) implemented in 14nm CMOS FinFET technology. The QSC includes an augmented general-purpose digital processor that supports waveform generation and phase rotation operations combined with a low power current-mode single sideband upconversion I/Q mixer-based RF arbitrary waveform generator (AWG). Implemented in 14nm CMOS FinFET technology, the QSC generates control signals in its target 4.5GHz to 5.5 GHz frequency range, achieving an SFDR > 50dB for a signal bandwidth of 500MHz. With the controller operating in the 4K stage of a cryostat and connected to a transmon qubit in the cryostat’s millikelvin stage, measured transmon T1 and T2 coherence times were 75.5μs and 73 μs, respectively, in each case comparable to results achieved using conventional room temperature controls. In further tests with transmons, a qubit-limited error rate of 7.76×10-4 per Clifford gate is achieved, again comparable to results achieved using room temperature controls. The QSC’s maximum RF output power is -18 dBm, and power dissipation per qubit under active control is 23mW. An improved, low power design version that achieves half of this power will also be presented.

  • 2024 IEEE CASS Seasonal School on “Intelligence in Chips: Memristive Sensing & Bioinspired Computing Systems”
     

    October 16-19, 2024, Online

    Description of the Seasonal School Technical Theme:

     

    We propose to organise the third seasonal school, continuing our highly successful CASS seasonal school in 2021 on “Intelligence in Chip: Tomorrow of IC” and 2022 on “Intelligence in Chips: Integrated Sensors and Memristive Computing”. Our past workshops were hosted by the Kerala chapter. This year, the German chapter proposes to organise this in its push to reinitiate activities in Germany, in partnership with colleagues from Italy and India.

    The 2021 school explored the future design of intelligence in IC while the 2022 workshop explored sensing and computing using memristors on a chip. In the third workshop, we will enhance the system element of intelligent sensing on a chip, particularly based on image sensing. A large number of proposed AI circuits aim to work on images and videos produced by CMOS image sensors, while being bioinspired. We aim to showcase the integration of these two circuit design approaches – that of image sensors and bioinspired computing approaches using novel memory elements of Memristors. We have planned a series of very concentrated seminars lasting 3 days on joint design of imaging and intelligence using traditional CMOS circuits jointly with Memristors. In addition to updates on design aspects of these, we will also concentrate on manufacturability of these devices, and we will train CASS student and wider membership on potential fabrication routes for such systems. In addition to training seminars, we also propose to have case studies of designing such systems from leading academic and industrial groups in the field.

    Motivation

    Implantable electronics play an essential role in the Advancement of medical devices. The introduction of the pacemaker in 1958 ushered in the era of active implants. Since then, numerous applications have benefited from Implantable electronics, such as cochlear implants and Nerve stimulators. With the advent of integrated circuits and new Manufacturing technologies, implantable electronics have Been used in new areas outside the healthcare industry. Over the years, a wealth of knowledge has accumulated in which specialized design techniques and circuits have been developed to meet the needs of implantable applications.

    Aim

    This Talk offers a comprehensive overview on the topic of implantable electronics. A primary focus is on presenting the special requirements and specifications of implantable electronics that arise from their respective applications, as well as an overview of the various techniques and methods used to meet these requirements. The electronic components of several implantable devices are presented, in addition to the corresponding manufacturing processes. Discussion of the technical aspects of implantable electronics will be followed by a discussion of the various applications, including emerging trends, directions and challenges.

He was also a co-founder of the Egyptian IEEE chapter for computational intelligence which received the best chapter award in 2009. In 2010 he joined the Institut für Mikroelektronik Stuttgart IMS CHIPS as a senior ASIC designer, where he was responsible for the development of novel circuits for camera systems, industrial sensors and biomedical intelligent implants for diagnosis and therapy for Bosch, Daimler, and other industrial clients. In addition, he was the scientific project director of various German and international research projects. In 2017 he founded the startup company Polymath Analog where he works in close cooperation with customers to provide innovative and reliable ASIC solutions for the Internet of Things, Industry 4.0 and automotive applications, with special emphasis on advanced analog design. He served as lead consultant for the development of a new generation of implantable image sensors for the company Retina Implant AG. In 2020 he joined the IU International University of Applied Sciences as a professor and founding chair of the electrical engineering program. He successfully led the development of the curriculum and the academic accreditation of the newly established department. He also serves as a scientific reviewer on several committees for the appointment of new Professors. Prof. Nawito is the author of several publications, including the textbook “CMOS Readout Chips for Implantable Multimodal Smart Biosensors (Springer)”.
