Design criteria for high temperature filters

Design Criteria for High Power Engines Crankshafts

The reliability of any mechanical system, in which the linear displacement of a piston is converted into the rotation of a power transmission shaft, strongly depends on the reliability of the crankshaft. The crankshaft is the critical component and any damage occurring to the crankshaft may put the mechanical system out of order. The numerical finite element simulation of crankshafts with multi...

Design for testability of high-order OTA-C filters

A study of oscillation-based test for high-order OTA-C filters is presented. The method is based on partition of a high-order filter into second-order filter functions. The opening Qloop and adding positive feedback techniques are developed to convert the second-order filter section into a quadrature oscillator. These techniques are based on an open-loop configuration and an additional positive...

Miniaturized High-Temperature Superconducting Microstrip and Coplanar Waveguide Filters

Two types of miniaturized high-temperature superconducting filters are described in this paper. The first type is developed by using small-sized microstrip spiral resonators, and the second type by coplanar waveguide quarter-wavelength resonators. The filters have significantly reduced size compared with many previous HTS filters. They are designed by employing an electromagnetic simulator in c...
