Multi- $V_{T}$ UTBB FDSOI Device Architectures for Low-Power CMOS Circuit

Abstract: This paper analyzes the potential of fully depleted silicon-on-insulator (FDSOI) technology as a multiple threshold voltage VT platform for digital circuits compatible with bulk complementary metal-oxide-semiconductor (CMOS). Various technology options, such as gate materials, buried oxide thickness, back plane doping type, and back biasing, were investigated in order to achieve a technology platform that offers at least three distinct VT options (high-VT, standard- VT, and low-VT ). The multi-VT technology platform highlighted in this paper was developed with standard CMOS circuit design constraints in mind; its compatibility in terms of design and power management techniques, as well as its superior performance with regard to bulk CMOS, are described. Finally, it is shown that a multi-VT technology platform based on two gate materials offers additional advantages as a competitive solution. The proposed approach enables excellent channel electrostatic control and low VT variability of the FDSOI process. The viability of the proposed concept has been studied through technology computer-aided design simulations and demonstrated through experimental measurements on 30-nm gate length devices.

Distribution Systems Reconfiguration Based on OPF Using Benders Decomposition

Abstract: This paper presents a new and efficient methodology for distribution network reconfiguration integrated with optimal power flow (OPF) based on a Benders decomposition approach. The objective minimizes power losses, load balancing among feeders, and is subject to constraints: capacity limit of branches, minimum and maximum power limits of substations or distributed generators, minimum deviation of bus voltages, and radial optimal operation of networks. A specific approach of the generalized Benders decomposition algorithm is applied to solve the problem. The formulation can be embedded under two stages: the first one is the master problem and is formulated as a mixed integer nonlinear programming problem. This stage determines the radial topology of the distribution network. The second stage is the slave problem and is formulated as a nonlinear programming problem. This stage is used to determine the feasibility of the Master problem solution by means of an OPF and provides information to formulate the linear Benders cuts that connect both problems. The model is programmed in the general algebraic modeling system. The effectiveness of the proposal is demonstrated through three examples extracted from the literature.
