Abstract: A junction termination with an internal field plate, the field plate structure and the junction termination extension region are folded inside the device to make full use of the thickness of the drift region in the body, thereby reducing the area of the termination and relieving the electric field concentration at the end of the PN junction. The breakdown position is transferred from the surface into the body of the original PN junction, and the withstand voltage of termination can reach to the breakdown voltage of the parallel plane junction. Under such design, a smaller area can be obtained than that of the conventional structure at the same withstand voltage.

Abstract: This invention relates to the field of communication technology, and particularly to a communication exchange mechanism design based on frequency hopping, which is applicable to cognitive radio networks. A method for generating hopping frequency sequences for multi-transceiver cognitive radio networks is provided, so as to realize the optimization and tradeoff of the five performance parameters, i.e. DoR, MTTR, AITR, CL, and NSS. That, is, for a given DoR, the frequency-hopping system should minimize the NSS of the clock synchronous and asynchronous frequency-hopping systems under the condition of MTTR=ATTR=1 and CL

Abstract: A device and a method are provided to automatically generate test case for embedded software. This invention is in software test field, including symbolic execution kernel module, path selection module, solver, debugger, concrete execution kernel module and debugger agent module. The tested software and test cases are uploaded from the host system to the embedded system through debugger and debugger agent. The concrete execution kernel module starts the tested software. The symbolic execution kernel module captures the run-time information of the tested software through the debugger. When the tested software operates on the symbol source, the symbolic execution kernel module marks the symbol source, tracks the symbol propagation, generates path condition and sends the path condition to path selection module. This invention can automatically generate test cases for embedded software, which doesn't need the source code of the tested software and can be conveniently used for commercial software.
