Ultrawideband LNA 1960–2019: Review by Shahab Shahrabadi

“…Its historical aspect illustrates when the idea of wideband LNA was born and how it changed to ultrawideband LNA, and its tutorial aspect discusses circuits and achievements to present optimum LNAs in Complementary MOS (CMOS), BiCMOS and High‐Electron‐Mobility Transistor (HEMT) technologies. This work describes the endeavours of engineers in reaching UWB LNA from narrowband LNA during six decades that have great importance as a chapter in understanding this topic because it teaches all topologies, techniques, circuits and related events in a historical narrative for trained readers who are not experts on this topic.…”

$${\mathbb{Z}}/2$$ Z / 2 topological invariants and the half quantized Hall effect by Bo Fu, Shun-Qing Shen

“…The $${\mathbb{Z}}/2$$ Z / 2 classification is determined by the line integral of the intrinsic anomalous Hall conductance, which is safeguarded by two distinct categories of local unitary and anti-unitary symmetries in proximity to the Fermi surface of electron states. We further validate the $${\mathbb{Z}}/2$$ Z / 2 topological order in the context of the quantized Hall phase by examining semi-magnetic topological insulator Bi2Te3 and Bi2Se3 film for ν = 1 and topological crystalline insulator SnTe films for ν = 2 or 4. …”
