A Single-Stage Quadrature LMVs [PDF]
International Journal of Electrical and Computer Engineering (IJECE), 2018 This paper proposes three kinds of single stage RF front-end, called quadrature LMVs (QLMVs), by merging LNA, single-balanced mixer, and quadrature voltage-controlled oscillator (VCO) exploiting a series LC (SLC) network. The low intermediate frequency (IF) or baseband signal near dc can be directly sensed at the drain nodes of the VCO switching ...

Gradient Harmonized Single-Stage Detector
Proceedings of the AAAI Conference on Artificial Intelligence, 2019 Despite the great success of two-stage detectors, single-stage detector is still a more elegant and efficient way, yet suffers from the two well-known disharmonies during training, i.e. the huge difference in quantity between positive and negative examples as well as between easy and hard examples.
