dc.descriptionObjective: In this work the design of a fourth-order Reconfigurable Sigma Delta analog-to-digital converter (ΣΔ ADC) for 5MHz, 7MHz or 10MHz channel bandwidths are presented. Materials and methods: Our design technique aims to keep the same ADC architecture in response to multi-band and multi-mode aspects of Mobile WiMAX standard. 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. This technique is intended to optimize the power and area of the ADC that efficiently covers varying channel bandwidths. Moreover, we use the pole placement method to calculate the optimized filter coefficients of Continuous-Time Sigma-Delta (CT ΣΔ) ADC. Results and discussion: Over 5MHz, 7MHz and 10MHz channel bandwidths, the ADC achieved 72.89dB, 67.26dB and 66.47dB peak SNR values, respectively and a dynamic range of 73.5dB, 69.47dB and 66.5dB respectively with only 28mW, 28.2mW and 28.6mW power consumption respectively. Conclusions: The design of the proposed reconfigurable ADC intended for use in the mobile WiMAX standard were achieved. Moreover, the results obtained are satisfactory and are in accordance with theoretical expectations.en-US

Materiales y métodos: nuestra técnica de diseño tiene como objetivo mantener la misma arquitectura de CAD en respuesta a los aspectos multibanda y multimodo del estándar móvil WiMAX. 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. Además, utilizamos el método de colocación de polos para calcular los coeficientes de filtro optimizados de Continuous-Time Sigma-Delta (CT ΣΔ) CAD. Resultados y discusión: El ancho de banda de canal de 5MHz, 7MHz y 10MHz alcanzó valores de SNR de pico de 72.89dB, 67.26dB y 66.47dB respectivamente, y un rango dinámico de 73.5dB, 69.47dB y 66.5dB, respectivamente, con solo 28mW, 28.2mW y 28.6mW consumo de energía respectivamente. Conclusiones: Se logró el diseño y la implementación del ADC reconfigurable propuesto para su uso en el estándar móvil WiMAX.
