Abstract: Two-dimensional layered materials and low-loss, high-quality on-chip functional devices formed by optical waveguides have received widespread attention in the field of integrated photonics.
Abstract: This paper proposes a 22–34 GHz neutralizationbased direct-conversion in-phase and quadrature (I/Q) upconverter implemented using a 90-nm CMOS process. The upconverter comprises two active ...
