MOSFET Model HiSIM Based on Surface-Potential Description for Enabling Accurate RF-CMOS Design
Miura-Mattausch, M.,Mattausch, H.J.,Ohguro, T.,Iizuka, T.,Taguchi, M.,Kumashiro, S.,Miyamoto, S. The Institute of Electronics and Information Engin 2004 Journal of semiconductor technology and science Vol.4 No.3
The origin of the phenomena, obstructing circuit performance in the RF operating regime, as well as their modeling will be discussed. The applied surface-potential-based modeling allows self-consistent description of all phenomena important for accurate circuit simulation, as demonstrated with the MOSFET model HiSIM.

K-Nearest Neighbor Associative Memory with Reconfigurable Word-Parallel Architecture
Fengwei An,Keisuke Mihara,Shogo Yamasaki,Lei Chen,Hans Jurgen Mattausch 대한전자공학회 2016 Journal of semiconductor technology and science Vol.16 No.4
IC-implementations provide high performance for solving the high computational cost of pattern matching but have relative low flexibility for satisfying different applications. In this paper, we report an associative memory architecture for k nearest neighbor (KNN) search, which is one of the most basic algorithms in pattern matching. The designed architecture features reconfigurable vector-component parallelism enabled by programmable switching circuits between vector components, and a dedicated majority vote circuit. In addition, the main time-consuming part of KNN is solved by a clock mapping concept based weighted frequency dividers that drastically reduce the in principle exponential increase of the worst-case search-clock number with the bit width of vector components to only a linear increase. A test chip in 180 ㎚ CMOS technology, which has 32 rows, 8 parallel 8-bit vector-components in each row, consumes altogether in peak 61.4 ㎽ and only 11.9 mW for nearest squared Euclidean distance search (at 45.58 ㎒ and 1.8 V).
