Abstract [en]

This paper addresses the different issues in the design of ADCs for future wireless handhelds. It reviews the constraints imposed on the receiver design by the low-power specifications in handhelds. The sigma-delta ADC architectures that can potentially be used for implementing future wireless handhelds are discussed in the perspective of a CMOS implementation. Finally, a 4(th) order 4bit continuous-time bandpass sigma-delta modulator capable of digitizing a WiMAX (20MHz) signal band centered at an IF of 75 MHz is presented. The simulation results shown that the proposed sigma-delta modulator can provide a SNDR of 50.1 dB and a DR of 56 dB at a sampling frequency of 500 MHz.
