Graphics Interchange format (w/ Alpha Channel Support) (If no Setup is indicated, the conversion requires no additional input.) If you do not specify conversion parameters, the defaults will be used. Some formats have a Setup in which you can set certain parameters for conversion. The following formats can be read by TurboCAD, either for import, export, or both. Click Run to convert all files in the selected folder and place the converted files in the target folder. Use the Files of type field to select the conversion format. Opens the TurboCAD File Converter window, in which you can select a source and destination folder for batch conversion. Seeįor a list of all supported CAD and Graphics file formats, File Converter To insert the contents of another file as a block, create an external reference (xref). For example, you can choose to import a drawing's layers and blocks, or export only print styles. To import or export only certain components of a file, use File / Extract From or Extract To. Browse to the folder and assign a file name.Under Save as type, select the format to which you want to export.Browse to the file, and double-click it or click Open.If you want to specify conversion parameters, click Setup.Under Files of type, select the format you want to import.You can import and export data from other TurboCAD formats, as well as formats of other CAD systems.

Resultados y discusion: El ancho de banda de canal de 5MHz, 7MHz y 10MHz alcanzo valores de SNR de pico de 72,89dB, 67,26dB y 66,47dB respectivamente, y un rango dinamico de 73,5dB, 69,47dB y 66,5dB, respectivamente, con solo 28mW, 28,2mW y 28,6mW consumo de energia respectivamente. ![]() Ademas, utilizamos el metodo de colocacion de polos para calcular los coeficientes de filtro optimizados de Continuous-Time Sigma-Delta (CT ) CAD. Para este fin, establecemos cada frecuencia de muestreo correspondiente a cada ancho de banda del canal, para que se mantenga el mismo valor OSR para las diferentes anchuras de banda del canal. Materiales y metodos: nuestra tecnica de diseno tiene como objetivo mantener la misma arquitectura de CAD en respuesta a los aspectos multibanda y multimodo del estandar movil WiMAX. Keywords: Continuous-time ADC, mobile WiMAX, reconfigurable ADC, regulated telescopic OTA, feedback DAC Objetivo: en este trabajo se presenta el diseno de un convertidor analogico a digital reconfigurable Sigma Delta ( CAD) de cuarto orden para anchos de banda de canal de 5MHz, 7MHz o 10MHz. Moreover, the results obtained are satisfactory and are in accordance with theoretical expectations. Conclusions: We achieved the design and implementation of the proposed reconfigurable ADC intended for use with the mobile WiMAX standard. Results and discussion: Over 5 MHz, 7 MHz and 10 MHz channel bandwidths, the ADC achieved 72,89 dB, 67,26 dB and 66,47 dB peak SNR values, respectively, and a dynamic range of 73,5 dB, 69,47 dB and 66,5 dB, respectively, with only 28 mW, 28,2 mW and 28,6 mW power consumption, respectively. Moreover, we use the pole placement method to calculate the optimized filter coefficients of continuous-time sigma-delta (CT ) ADC. ![]() This technique is intended to optimize the power and area of the ADC to efficiently cover varying channel bandwidths. To this end, we set each sampling frequency corresponding to each channel bandwidth, in order that the same OSR value would be kept for the different channel bandwidths. Materials and methods: Our design technique aims to keep the same ADC architecture in response to multi-band and multi-mode aspects of the mobile WiMAX standard. Abstract : Objective: In this work the design of a fourth-order reconfigurable sigma delta analog-to-digital converter ( ADC) for 5 MHz, 7 MHz or 10 MHz channel bandwidths is presented.
