Abstract: Implantable microelectronic devices (IMD) and neuroprostheses are finding applications in new therapies thanks to advancements in microelectronics, microsensors, RF communications, and medicine, which have resulted in embedding more functions in IMDs that occupy smaller space and consume less power, while offering therapies for more complex diseases and disabilities. I will address the latest developments in key building blocks for state-of-the-art IMDs, particularly on the analog front-end, RF back-end, and power management. IMDs have been quite successful in neuroprosthetic devices, such as cochlear implants and deep brain stimulators. They have been recently approved for vision and are being considered for brain-computer interfacing (BCI) to enable individuals with severe physical disabilities to control their environments, particularly by accessing computers. Implantable BCIs, however, are highly invasive and should be used when there are no less invasive alternatives that would offer similar benefits. They can also be utilized as advanced tools for neuroscience research on freely behaving animal subjects. I will talk about the example of a smart cage, which can wirelessly power, communicate with, and track sensors implanted in or attached to small freely behaving animals. At the same time, novel minimally-invasive methods are being explored for individuals with severe paralysis to make the best use of their remaining abilities to control their environments. An example of such technologies is a wireless and wearable brain-tongue-computer interface (BTCI), also known as the Tongue Drive System (TDS), which enables individuals with tetraplegia to control their environments using their voluntary tongue motion.

Abstract: Point-of-use biological/chemical assays are aimed to transform the bulky laboratory instruments into facile lab-on-a-chip platforms, bringing down the cost, size and sample-use by orders of magnitude. A micro-Nuclear Magnetic Resonance (NMR) CMOS transceiver enables repeatable, versatile and low cost screening of samples as it is label-/washing-free, and immobilization-free for the electrodes. Herein, two lab-on-CMOS NMR systems are presented: the first facilitates multi-step multi-sample management by electronic-automated digital microfluidics, whereas the second benefits from magnetic-field stabilization and thermal management to unify multi-type assays (target detection, protein state analysis and solvent-polymer dynamics) in a handheld scale suitable for healthcare, food industry and colloidal applications. The detection limit is down to 50pM for E. faecalis derived DNA. The platform consumes 120x less sample, and is 96x lighter, 175x smaller and 16x cheaper than a 135kg commercial product.

Abstract: Highly scaled nanometer CMOS technologies pose serious challenges for the design of analog integrated circuits. The reducing voltage headroom forces power and area consumption to rise instead. The improving timing resolution however comes to the rescue. Time-based solutions use fast digital circuits to implement power- and area-efficient solutions for analog circuits without large and power-hungry analog building blocks. This principle will be illustrated for CMOS sensor interface design, as needed in many present-day and emerging applications such as automotive, wireless sensor networks and internet of things. This talk will present basic time-based architectures and discuss their capabilities and fundamental performance limitations. This will be illustrated with several actual designs, for both medium and high resolutions.
