Author(s): Lucrezia Navarin, Karl Norling, Marco Parenzan, Stefano Ruzzu, Andrea Neviani, Andrea Bevilacqua

Abstract:

A fully integrated galvanic isolator for gate drivers that supports high-speed, asynchronous, full-duplex communication is presented. Data transmission from the microcontroller to the power device is achieved using amplitude-shift keying (ASK) at 100 Mb/s, while simultaneous communication in the opposite direction is implemented using frequency-shift keying (FSK) at 167 Mb/s. …

A 302.5-GHz 30.9-dB-Gain THz Amplifier in 65-nm CMOS

A 302.5-GHz 30.9-dB-Gain THz Amplifier in 65-nm CMOS 150 150
Author(s): Yu-Kai Chen, Yi-Fan Tseng, Wei-Zhe Su, Chun-Hsing Li

Abstract:

A 302.5-GHz high-gain CMOS THz amplifier is proposed in this work. An electromagnetic (EM) modeling approach, verified by transistor measurements, is employed to optimize transistor layout, effectively reducing gate resistance and drain-to-gate capacitance. This significantly enhances the transistor’s maximum oscillation frequency $f_{mathrm {max }}$ from 239.7 to 367.5 GHz. Furthermore, a $…

Cryogenic Hyperdimensional In-Memory Computing Using Ferroelectric TCAM

Cryogenic Hyperdimensional In-Memory Computing Using Ferroelectric TCAM 150 150
Author(s): Shivendra Singh Parihar, Shubham Kumar, Swetaki Chatterjee, Girish Pahwa, Yogesh Singh Chauhan, Hussam Amrouch

Abstract:

Cryogenic operations of electronics present a significant step forward to achieve huge demand of in-memory computing (IMC) for high-performance computing, quantum computing, and military applications. Ferroelectric (FE) is a promising candidate to develop the complementary metal oxide semiconductor (CMOS)-compatible nonvolatile memories. Hence, in this work, we investigate the effectiveness …

A Multi-Core Series-Resonance CMOS Oscillator

A Multi-Core Series-Resonance CMOS Oscillator 150 150
Author(s): Shiwei Zhang, Wei Deng, Haikun Jia, Zhihua Wang, Baoyong Chi

Abstract:

Multi-core and series-resonance (SR) techniques have been proposed to achieve ultra-low phase noise (PN) performance. In this article, a scalable ring-coupling scheme is proposed for multi-core expansion. The mechanism provides intrinsic oscillation and PN reduction without compromising the passive network, specifically tailored for the SR oscillator. The dual closed ring …
