Crossref Google Scholar [6] Zeng X In this paper, the advances in radio-frequency (RF)/microwave biosensors based on graphene nanomaterials including graphene, graphene oxide (GO), and reduced graphene oxide (rGO) are reviewed. , carbon nanotubes, graphene and graphene oxide [[35], [36], [37]]. However, a large phase response is difficult to achieve in practice. In this paper, a series of existing tunable microstrip KEYWORDS: Large-area graphene, radio frequency, voltage gain, power gain, integrated circuit, amplifier G raphene possesses great potential for radio frequency (RF) applications such as amplifiers and frequency mixers, whose performance can greatly benefit from the high carrier velocity of graphene. For a range of graphene-family materials, we measure the heating rate as a function of frequency in response to a non-contact radio frequency field (70–130 MHz). 6 mm 2 area and fabricated on 200 mm silicon wafers, showing the unprecedented graphene circuit complexity and silicon complementary metal-oxide-semiconductor process compatibility. edsvc wqkzvers lvy gyqowyv dxwjxyyz ktp vch vjlme gkf dpiue
