Abstract

This paper proposes a multiplexing scheme to realize an I/Q channel time-interleaved (TI) band-pass sigma-delta modulator (BPSDM) that shares OTAs to minimize power consumption and silicon area for a low-IF wireless receiver. The test chip was fabricated for a 10.7-MHz IF system with a 0.35-μm CMOS process. The measured peak SNDR for a 200-kHz bandwidth is approximately 73 dB. The power consumption of the fabricated chip is 61 mW with a 3.3-V supply and the silicon area is 1.78 mm2.
