DOI: 10.1109/tcsi.2022.3206837
Abstract: Fractional-N phase-locked loops using Harmonic-Mixer (HM) based feedback offer good phase noise and spur performance without relying on complex calibration schemes. The HMs in prior art are often realized using the Sample-and-Hold (S/H) operation. This,… read more here.

DOI: 10.1109/tmm.2021.3123813
Abstract: Key semantics can come from everywhere on an image. Semantic alignment is a key part of few-shot learning but still remains challenging. In this paper, we design a Mixer-Based Semantic Spread (MBSS) algorithm that employs… read more here.
