In this paper, on-wafer de-embedding methods for passive components are evaluated for millimeter wave integrated circuit (MMW IC) design support. An electromagnetic simulation aided de-embedding (EMSAD) technique is proposed. The electromagnetic model is calibrated by matching the open-short de-embedded measurement at relatively lower frequencies. A set of Ground Coplanar Waveguide (GCPW) test structures...
In this paper, we address a haze removal problem from a single nighttime image, even in the presence of varicolored and non-uniform illumination. The core idea lies in a novel maximum reflectance prior. We first introduce the nighttime hazy imaging model, which includes a local ambient illumination item in both direct attenuation term and scattering term. Then, we propose a simple but effective image...
Electrical arcs are of great concern for power electronic systems. Modeling of arc faults to represent and predict arc characteristics and transient responses within the power system is now receiving considerable research attention. In this paper, a series DC arc fault demonstration rig is designed to generate series arcs by moving one electrode away from a stationary one with a stepper motor. Experimental...
Taking into account the shortcomings of traditional three-phase full-wave rectifier method, a new method which achieves the trigger control of the three-phase Silicon Controlled Rectifier (SCR) half-controlled bridge by means of the PIC Single Chip Microcomputer (SCM) is presented. In this method, SCM is used to detect zero-crossing point of the voltage and control the one-phase SCR delay trigger...
