  • The drain current reduction effect due to the side-gating phenomena resulted from interaction between the neighbor gates is lead to degradation of circuit performance. In this paper, these effect were modelized for circuit simulation with the shift of threshold voltage resulting from negative charge formation and the analysis of substrate leakage current resulting trapping effect. To remove dificiencies of the conventional three terminal structure, these model were implemented in SPICE with the four terminal structure, and then the constructed environment enables the simulation of circuit performance degradation resulted from side-gating effect. The validity of implemented model is proved by comparisoin with experiment data.

  • 1. Purpose This study is intended to catch the expasion of theory of Sasang Constitutional Medicine through Dongyi-Soose-Bowon Chopanbon with Sasang-Yihak-Chobonguen and Dongyi-Soose-Bowon Gapobon 2. Method I studied the archive of prescription and medicines concerned in the Dongyi-Soose-Bowon Chopanbon with Sasang-Yihak-Chobonguen and Dongyi-Soose-Bowon Gapobon 3. Result and conclusion 1. The principle which select the Sasang-in Prescription in Dongmuyugo is Hyung-Choei-Eik-Mi(馨臭液味) and Seung-Gang-Gae- Hap(升降開闔) 2. The same Medicine in Dongyi-Soose-Bowon Chopanbon and Sasang-Yihak-Chobonguen and Dongyi-Soose-Bowon Gapobon is 27 and this medicines are the principle medicine in the Taiyin Disease 3. The same Herb-Medication in the Sasang-Yihak-Chobonguen and Dongyi-Soose-Bowon Gapobon is 4 and the concept in the Sasang-Yihak-Chobonguen is succeded to Dongyi-Soose-Bowon Gapobon 4. The same Herb-Medication in the Dongyi-Soose-Bowon Gapobon and Dongyi-Soose-Bowon Chopanbon is 7 and the Change between the Dongyi-Soose-Bowon Gapobon and Dongyi-Soose-Bowon Chopanbon is the cognition between the Pyozeung(表證) and Lizeung(裏證) in the disease 5. There is no same Herb-Medication in that three books. This result can prove that the Dongyi-Soose-Bowon Chopanbon's New Herb-Medication(新定方) was made in the last stage of Sassng-Yihak
