Low Power-Consumption and High Response Frequency Thermo-Optic Variable Optical Attenuators Based on Silicon-on-Insulator Materials

The new communication markets are vey demanding: high frequency, high degree of integration, low power consumption. Silicon-on-Insulator offers many advantages and this paper illustrates the potentialities of this technology for RF and microwave applictions. After an overview of the SOI material, the properties of the SOI MOSFET's are analyzed and compared to bulk Si MOSFET's. The models of transmission lines and inductors on SOI are compared and further used in the on-wafer characterization of the transistors. Various models for the transistors are presented and their limitations are given. A new model is described, valid from DC to the microwave region. This model agrees very well with the measurements for various transistor dimensions. Finally, variuos RF and microware circuits are presented. Ths paper does not fully describe all the properties and applications of SOI but the numerous references offered to the reader help him to gather more informations.

Shim Coil

It is necessary to develop a high homogeneous, low power consumption, high frequency and small-size shim coil for high precision and low-cost atomic spin gyroscope (ASG). To provide the shim coil, a multi-objective optimization design method is proposed. All structural parameters including the wire diameter are optimized. In addition to the homogeneity, the size of optimized coil, especially the axial position and winding number, is restricted to develop the small-size shim coil with low power consumption. The 0-1 linear programming is adopted in the optimal model to conveniently describe winding distributions. The branch and bound algorithm is used to solve this model. Theoretical optimization results show that the homogeneity of the optimized shim coil is several orders of magnitudes better than the same-size solenoid. A simulation experiment is also conducted. Experimental results show that optimization results are verified, and power consumption of the optimized coil is about half of the solenoid when providing the same uniform magnetic field. This indicates that the proposed optimal method is feasible to develop shim coil for ASG.
