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 $…

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 …
