Abstract

This paper describes a receive baseband ADC for a GSM cellular radio system. The circuit consists of two second-order double-sampled semi-bilinear ΣΔ modulators followed by two 576-tap digital FIR GSM-channel filters with offset calibration. The complete A/D achieves a dynamic range of 72 dB and dissipates 11.8 mW from a 2.7 V supply. The area is 1.6 mm² in a 0.5 μm N-well double-poly, triple-metal CMOS process
