Design of a Reconfigurable ADC for UWB/Bluetooth Radios
2008 (English)In: 2008 Joint IEEE North-East Workshop on Circuits and Systems and TAISA Conference, NEWCAS-TAISA: Montreal, QC; 22 June 2008 through 25 June 2008, New York: IEEE , 2008, 205-208 p.Conference paper (Refereed)
This paper presents the circuit implementation of a reconfigurable Analog to Digital Converter (ADC) for UWB and Bluetooth communication standards for mobile terminals. The bandwidth accuracy space is covered through smart configuration of a flexible capacitive interpolation ADC, used as stand-alone in UWB mode and as quantizer of a Sigma Delta ADC in Bluetooth mode. The ADC has been accurately modeled in Matlab/Simulink and then implemented at transistor level in a 180 nm CMOS process in the Cadence environment. The simulation results indicate that the ADC can achieve 30 dB SINAD at 528 MSPS in UWB mode, and 60 dB SINAD at 1 MSPS in Bluetooth mode.
