Singh, G.D. (author), Nemati, Hossein Mashad (author), Alavi, S.M. (author), de Vreede, L.C.N. (author)This paper proposes a power amplifier (PA) correction technique to recover from load mismatch. It utilizes a main PA, two auxiliary PAs, and a coupler. By adjusting the input drive levels of the PAs it can recover the output power and to a great extent the efficiency of the main PA even when exposed to 2:1 VSWR mismatch conditions. When...conference paper 2023

Shirekar, Ojas Kishorkumar (author), Singh, Anuj (author), Jamali-Rad, H. (author)Humans have a unique ability to learn new representations from just a handful of examples with little to no supervision. Deep learning models, however, require an abundance of data and supervision to perform at a satisfactory level. Unsupervised few-shot learning (U-FSL) is the pursuit of bridging this gap between machines and humans. Inspired...conference paper 2023
