This paper proposes a circuit structure which can improve signal-to-noise ratio of a conventional common-gate CMOS LNA for UWB (Ultra-Wide-Band; 3.1-10.6 GHz) using 0.18 um CMOS technology. The simulated results show that the proposed circuit has gain of 16.3-18.8 dB and NF of less than 3dB as well as good compatibility with input matching in a wide(More)
A 38-year-old male suffered from swelling of the lower lip for 3 months. Neither facial nerve palsy nor fissuring of the tongue was present. Histological examination of a biopsy taken from the lower lip revealed non-caseous epithelioid cell granulomas, suggestive of cheilitis granulomatosa. Patch testing revealed positive reactions to mercury chloride and(More)
