Ultra-Low Power Circuits And Architectures For Neuromorphic Computing Accelerators With Emerging Tfets And Rerams, Jie Lin Jan 2020

Ultra-Low Power Circuits And Architectures For Neuromorphic Computing Accelerators With Emerging Tfets And Rerams, Jie Lin

Electronic Theses and Dissertations, 2020-

Neuromorphic computing using post-CMOS technologies is gaining increasing popularity due to its promising potential to resolve the power constraints in Von-Neumann machine and its similarity to the operation of the real human brain. To design the ultra-low voltage and ultra-low power analog-to-digital converters (ADCs) for the neuromorphic computing systems, we explore advantages of tunnel field effect transistor (TFET) analog-to-digital converters (ADCs) on energy efficiency and temperature stability. A fully-differential SAR ADC is designed using 20 nm TFET technology with doubled input swing and controlled comparator input common-mode voltage. To further increase the resolution of the ADC, we design an energy …


Thin-Film Lithium Niobate Integrated Photonics On Silicon For Electro- And Nonlinear-Optic Applications, Amirmahdi Honardoost Jan 2020

Thin-Film Lithium Niobate Integrated Photonics On Silicon For Electro- And Nonlinear-Optic Applications, Amirmahdi Honardoost

Electronic Theses and Dissertations, 2020-

In order to overcome the drawbacks associated with conventional bulk lithium niobate photonic, thin-film lithium-niobate-on-silicon has been pursued recently. This work presents contributions made to electro-, and nonlinear-optic applications of this technology. For electrooptic applications, detailed modeling and design guidelines of optical and radio-frequency parameters of ultracompact modulators are developed and their accuracy in predicting the high-speed performance of such devices have been verified by comparison with experimental results. Novel design techniques and pathways for ultrahigh-speed (sub-terahertz) operation of such modulators, achieving up to 400 GHz modulation bandwidth, are also presented. For optical interconnect applications, novel structures for ultralow-power consumption …
