Abstract [en]

A low-distortion sigma-delta analog-to-digital converter (ADC) for Wireless Local Area Network (WLAN) standards is presented. The proposed sigma-delta modulator architecture employs the 4-bit 2(nd) order sigma-delta modulator with swing suppression in a 2-2 modified cascaded configuration, which greatly improves the tonal behavior even at 8X oversampling ratio (OSR). The modulator is designed in 0.18um CMOS process and operates at 1.8V supply voltage. It achieves a dynamic range of 69.1dB and a spurious free dynamic range (SFDR) of 82.2dB for a 10MHz signal bandwidth, and an oversampling ratio of 8.
