A modified low power auto-adaptation unit for reconfigurable analog to digital converter in wireless applications

Abstract

In the present work, a modified auto-adaptation unit is presented for switching between different wireless standards. The adaptation unit provides an architectural level flexibility to reconfigure the resolution of the analog to digital converter, irrespective of the converter circuit. The adaptation unit generates control bits that give the measure of the input wireless standard and provide the reconfigurable ADC, an ability to work on different modes. The paper utilizes the autoadaptation concept in the area of wireless applications for GSM, WCDMA and WLAN standards with band limited to 10MHz. The power consumption for the modified circuit is 106.4μW. The simulative analysis has been carried out for 180nm technology node using Cadence EDA tools.
