The performance characteristics of transmission lines, silicon integrated waveguides, tunable LC resonators and passive combiners/splitters and baluns are described in this paper. It is shown that Q-factor for an on-chip LC tank peaks between 20 and 40 GHz in a 65 nm RF-CMOS technology; well below the bands proposed for many mm-wave applications.(More)
BACKGROUND The aim of this study is to describe point-of-care ultrasound and Color flow Duplex Doppler characteristics of penetrating and blunt trauma-related vascular injuries of the limbs and neck. METHODS Penetrating and blunt trauma-related vascular injuries such as vein disruption, intimal flap, deep vein thrombosis, arterial dissection,(More)
BACKGROUND The aim of this study is to assess the accuracy of a Fast Doppler protocol for the examination of an injured lower limb, namely 2-Point Fast Doppler (2PFD), in order to rapidly triage arterial lesions after penetrating trauma. METHODS The presence of flow and the aspects of the Doppler waveform of the dorsalis pedis artery (DPA) and posterior(More)
