High Resistivity SOI MOS 버랙터를 위한 RF 대신호 모델 연구
홍서영(Seoyoung Hong),이성현(Seonghearn Lee) 대한전자공학회 2016 전자공학회논문지 Vol.53 No.9
RF 채널 분포효과를 위한 전압 종속 외부 게이트 커패시턴스가 사용된 High resistivity(HR) silicon-on-insulator(SOI) RF accumulation-mode MOS 버랙터의 대신호 모델이 새롭게 개발되었다. 이 모델의 전압 종속 파라미터들은 정확한 S-파라미터 optimization을 사용하여 추출되었고, 이를 피팅하여 empirical 모델 방정식을 구축하였다. 이러한 새로운 대신호 RF 모델은 넓은 전압영역에서 측정된 Y11-파라미터 데이터와 20 GHz까지 잘 일치함으로써 정확도가 검증되었다. A new large-signal model including the voltage-dependent extrinsic gate capacitance for RF channel distribution effect is developed for a high resistivity(HR) silicon-on-insulator(SOI) RF accumulation-mode MOS varactor. The data of voltage-dependent parameters are extracted by using accurate S-parameter optimization, and empirical model equations are constructed by data fitting process. The RF accuracy of this new model is validated by observing excellent agreements between modeled and measured Y11-parameter data in the wide voltage range up to 20 GHz.

There is no agreement of opinion that whiplash injury caused by traffic accident result in cerebrovascular diseases and no legal basement.We report an unusual case of 55-years-old woman with cerebral infarction following whiplash injury, and who had no risk factor of cerebrovascular disease.We conclude that decrease of cervical lordotic curve and internal carotid arterial impingement against the lateral mass of the atlas and transverse processes of the spine can result in internal carotid arterial dissection and a embolus made by this mechanism cause ischemic state of the cerebrum.The patient was treated by optimal management-such as chuna, herb medicine, acupuncture, and physical treatment-, and shoud be need long-term observation.
