Design of Energy-Efficient Equalization and Data Encoding/Decoding Techniques for Wireline Communication Systems

Creator:: Chun, Yu Sang
Abstract:: Ever increasing global internet data traﬃc has driven up the demand for cutting-edge high-speed wireline communication systems including SerDes PHY for various interfaces, interconnects, data centers servers and switches in optical systems. Operating wireline communications at higher data rates leads to signals suﬀering from greater channel loss and exponential increase...

A new data encoding scheme for equalization - Integrated Pulse Width Modulation (iPWM)

Creator:: Ramachandran, Ashwin
Abstract:: This work presents a new data encoding scheme: Integrated Pulse Width Modulation (iPWM) for equalizing lossy wireline channels with the aim of achieving energy efficient wireline communication. The proposed scheme is able to overcome the fundamental limitations imposed by Manchester and Pulse Width Modulation (PWM) encoding on high data rate...

An Inductor-Less Multiple Input Single Output (MISO) Energy Harvester Achieving 74.6% Efficiency with Simultaneous MPPT

Creator:: Devaraj, Abhishekh
Abstract:: This work presents an inductor less switched capacitor based energy harvester, which can simultaneously harvest from 2 energy sources (Solar + Piezo). The proposed harvester employs 2D maximum power point tracking algorithm, by changing the conversion ratios of the charge pumps for piezo and solar sources, and 1D voltage regulation...

A Wide Modulation Range and PVT-Tolerant Spread-Spectrum Modulation Clock Generator

Creator:: Sun, Hyuk
Abstract:: This dissertation presents a phase domain in-loop-bandwidth spread-spectrum clock generation technique. In this proposed technique, a charge-based discrete-time loop filter is proposed to enable the phase domain in-loop-bandwidth spread-spectrum modulation without a delta-sigma modulator or time-to-digital converter. The in-loop-bandwidth modulation technique maximizes the loop bandwidth to improve phase noise suppression...

Leveraging transformer encoder output for effective token summary in simultaneous translation

Creator:: Raffel, Matthew
Abstract:: Simultaneous speech-to-text translation remains a difficult yet important problem for modern machine learning models whereby a text translation is generated concurrently with receiving partial speech inputs. One state-of-the-art simultaneous speech-to-text model is the augmented memory transformer whose encoder breaks a speech input into fixed-size overlapping segments composed of left, right,...

A 1V 40mA Fast Transient Capless LDO with 7uA Quiescent Current in 180nm CMOS using Ring Amplifier with Adaptive Damping

Creator:: Xiao, Bohui
Abstract:: Ring amplification has emerged as an efficient technique to drive large capacitive loads in switched capacitor circuits. We propose circuit techniques to demonstrate the first application of a ring amplifier in a non-capacitive feedback system of a LDO. These techniques enable a simple cap-less LDO structure in 180nm CMOS that...

Energy-efficient OTA architectures using load-pole cancellation

Creator:: Ramakrishna, Pavan Kumar
Abstract:: The CMOS two-stage Operational Transconductance Amplifier (OTA) has been a key enabler for mixed-signal IC design for nearly four decades . This research focuses on a modified two-stage CMOS OTA that features load-pole cancellation (LPC); i.e., the resulting architecture is essentially a two-stage CMOS OTA with no load capacitance. The...
