Abstract

In this paper we present a design methodology for optimizing the power consumption of continuous-time (CT) ΣΔ A/D converters. A method for performance prediction for ΣΔ A/D converters is presented. Estimation of analog and digital power consumption is derived and employed to predict the most power efficient configuration of a CT single-loop ΣΔ ADC. Finally, a 10 bit prototype converter is optimized and simulated using a 0.35 μm CMOS technology. The simulation results of the prototype 1.8 V converter show a SNR better than 65 dB and a spurious-free dynamic range of more than 63dB, consistent with 10 bits performance. Expected power consumption for the prototype is approx. 170 μW.
