Abstract

This paper proposes a low power dual-mode sigma-delta (ΣΔ) modulator for GSM and WCDMA receivers. The proposed modulator satisfies both standards by modifying the transfer function without changing sampling frequency or the loop order. The simulation results show 85 dB dynamic range for a GSM mode and 55 dB for a WCDMA mode. The proposed modulator is designed in a 0.35 μm CMOS process and consumes 5.5 mW of power under 1.8-V supply.
