Cascoded Active Quencher for SPADs With Bipolar Differential Amplifier in 0.35 μm BiCMOS

open access: yesIEEE Photonics Journal, 2022
Fast active quenching of single-photon avalanche diodes (SPADs) is important to reduce the afterpulsing probability (APP). An option to reduce the reaction time of electronics to a SPAD's avalanche is to design a quencher exploiting bipolar ...

A Novel Low Dynamic Resistance Dual-Directional SCR With High Holding Voltage for 12 V Applications

open access: yesIEEE Journal of the Electron Devices Society, 2020
The excellent area efficiency of dual-directional SCRs (DDSCRs) have made them desirable for low-voltage and high-voltage applications. However, to implement the required symmetrical structure, conventional DDSCRs have to lengthen their ESD discharge ...

Understanding and Tuning Mobile Interfaces in Ferroelectric Hf0.5Zr0.5O2 Thin Films in Relation to Microstructure

open access: yesAdvanced Functional Materials, EarlyView.
Ferroelectricity in thin HfO2‐based films offers great possibilities for next‐generation neuromorphic memory devices. There, the response to subcoercive voltage signals is driven by the movement of mobile interfaces and their interaction with crystal defects – a yet rather unexplored aspect, which we shed light on and gain new insights into the complex

A Perspective on Symmetric Lateral Bipolar Transistors on SOI as a Complementary Bipolar Logic Technology

open access: yesIEEE Journal of the Electron Devices Society, 2015
Recently published reports suggest that symmetric lateral bipolar transistors on semiconductor-on-insulator (SOI) is CMOS compatible in fabrication process, and can be much denser than CMOS due to their much larger (5-10× larger) drive-current ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

open access: yesAdvanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.
