IEEE PCJS SSCS DL : Dr Hsieh : “Digitally Enhanced Clock Generation and Distribution”

Virtual: https://events.vtools.ieee.org/m/420963

Advancements in technology scaling have ushered in larger systems boasting enhanced functionality, increased operational speed, and expanded data bandwidth. However, these benefits come with more demanding clocking requirements, including extended distribution distances and heightened timing precision. Furthermore, technology scaling has rendered traditional analog design challenging. Wider PVT variations necessitate intensive calibration efforts, and increased integration levels call for resilience against external noise sources. Moreover, the fact that reference frequency and loop bandwidth do not scale at the same rate as technology leads to prohibitive costs for oversized loop filters. While pure analog implementations offer intuitive operation and elegant analysis, clocking circuits incorporating digital elements offer effective solutions to these challenges. This presentation will cover how digital circuits can enhance clock generation and distribution through techniques like calibration and signal processing. Beginning with well-established methods that harness the mixed-signal nature of PLLs, such as delta-sigma modulation for the MDD in fractional-N PLLs, the presentation will shift toward digital-intensive architectures. It will focus on techniques that leverage digital implementations for error detection and enhance timing accuracy through either analog or digital correction. State-of-the-art designs featuring runtime calibration and power noise cancellation for clock generation and distribution will also be introduced. This talk will conclude with insights into future challenges and trends. Speaker(s): , Ping-Hsuan Hsieh Agenda: 8pm - 9pm : DL and Q/A Virtual: https://events.vtools.ieee.org/m/420963

Low Frequency Signal Integrity with Hardware Demonstrations

TÜV Rheinland North America, Technology and Innovation Center, 400 Beaver Brook Road , Boxborough, Massachusetts, United States, 01719

Abstract: Since most electrical engineers and PCB designers did not learn about low frequency signal integrity and grounding in school, it can be challenging for them to achieve good low frequency signal integrity that is vital to the performance of closed-loop systems. Precision measurements and A/D conversion of temperature, flow, pressure, current, and voltage in modern energy conversion and motion control systems are simply not possible without excellent low frequency signal integrity. During this presentation, using a signal generator, current and magnetic field probes, and an oscilloscope, Lee will model, demonstrate, and measure the signal integrity, emissions, and immunity problems that can arise in low frequency circuits.

Retro Gaming on the Atari

Bldg: RICM Entrance, Lower level, rear of building, 1755 Bald Hill Road, Warwick, Rhode Island, United States, 02886

The Providence Section of the IEEE is joining with the Rhode Island Computer Museum (RICM) to host a "Retro Gaming on the Atari" event on June 19, 2024. Anyone interested in the origins of video gaming, and those who remember the origins will have the chance to experience playing on the original equipment at this event. The Providence Section will provide pizza and soda. This is an opportunity for anyone interested in IEEE's mission - "Advancing Technology for Humanity" - to network, and to speak with local members about both planned and possible future events. Games on at 6 PM / Games off at 9 PM / Suggested Donation to RICM $10 Co-sponsored by: Rhode Island Computer Museum Bldg: RICM Entrance, Lower level, rear of building, 1755 Bald Hill Road, Warwick, Rhode Island, United States, 02886
