Friday Seminar: Catalyzing Computing for Brain-Computer Interfaces

Abstract: Brain-computer interfaces will help us treat brain disorders, augment the healthy brain, and shed light on how the brain as an organ gives rise to the mind. Delivering on this promise requires the design of computer systems that delicately balance the tight power, latency, and bandwidth trade-offs needed to decode brain activity, stimulate biological neurons, and control assistive devices most effectively. This talk presents my group's design of a standardized and general computer architecture for future brain interfacing. Our design enables the treatment of several...

Friday Seminar: 2×2 MIMO 802.11a/b/g/n/ac Simultaneous Dual-Band and 802.11ax Triple-Band WLAN Transceivers with up to +29 dBm Psat Integrated Power Amplifiers

Abstract: This presentation describes a dual-band 2X2 MIMO 802.11a/b/g/n/ac WLAN RF transceiver capable of simultaneous dual-band operation and a triple-band 2X2 MIMO 802.11ax WLAN RF transceiver. The measured receiver sensitivity of 2 GHz at 54 Mbps is -78.3 dBm and of 5 GHz for VHT80 is -66 dBm. The 802.11ac 2 x 2 MIMO 20-MHz MCS0 2 and 5 GHz receiver sensitivity levels are -96 and -95.5 dBm, respectively. Integrated power amplifiers with Psat up to +29 dBm enable the 2-GHz transmitters to achieve TX output power of +23.5 dBm at 54-Mbps 64-quadratic-amplitude modulation (...

Friday Seminar: A 384-Site Chip Platform for Biochemical Applications with Individual Site Precision Temperature Control

Abstract: A chip platform for thermally controlled biochemistry is presented and comprises post-processed thermally-isolated heated reaction sites atop an ASIC using PID feedback temperature control. The 384 sites can be individually programmed over 25-125°C, with thermal crosstalk below the +/- 0.12°C precision. Double-strand DNA purification via selective melting is demonstrated, with 70% retention of perfectly matched sequences, while 55% of those with two mismatched base-pairs are removed.

Friday Seminar | Building the Metaverse: Augmented Reality applications and integrated circuits challenges

Abstract:Augmented reality is a set of technologies that will fundamentally change the way we interact with our environment. It represents a merging of the physical and the digital worlds into a rich, context aware and accessible user interface delivered through a socially acceptable form factor such as eyeglasses. One of the biggest challenges in realizing a comprehensive AR and AI experiences are the performance and form factor requiring new custom silicon. Innovations are mandatory to manage power consumption constraints and ensure both adequate battery life and a...

Friday Seminar: DiffuserCam: Multi-dimensional Lensless Imaging

Abstract:

We describe a computational camera that enables single-shot multi-dimensional imaging with simple hardware and scalable software for easy reproducibility. We demonstrate compact hardware and compressed sensing reconstructions for 3D fluorescence measurements with high resolution across a large volume, hyper-spectral imaging, and temporal super-resolution – recovering a video from a single-shot capture. Our inverse algorithms are based on large-scale nonlinear non-convex optimization combined with unrolled neural networks. Applications demonstrated include...

Friday Seminar: Shaping the Future with Electromagnetics: From Intelligent Sensing to Automated Design

Abstract: The ability to understand, harness, and manipulate electromagnetic fields has driven groundbreaking technological advancements in the nearly 200 years since Maxwell’s equations were formulated. The 21st century alone has witnessed remarkable progress across computing, communications, and precision healthcare, fueled by advances in both circuits and electromagnetics. Improved manufacturing and nanofabrication techniques have pushed performance boundaries, with silicon CMOS integrated circuits emerging as an ideal platform for innovation—seamlessly integrating sensing...

Friday Seminar: Transceivers for Optical Communications in the Age of AI

Ray Nguyen

Abstract:

The post-Covid era has enjoyed an unprecedented rise in high bandwidth consumption activities such as remote working, streaming, VR, and AR. With the recent breakthroughs in AI and introduction of ChatGPT, data transport and interconnect fabrics of data centers are being stressed to the limits and forced to scale up even more rapidly than their traditional pace. In this talk, we revisit historical wireline trends in the last 20 years and their challenges, as well as give some of Marvell recent success stories on how these new frontiers are being tackled
