• A 2-2 cascaded Sigma-Delta modulator with 4-bit internal quantizers digitizes WLAN signals with 40MSPS conversion rate. Implemented in 90nm CMOS using nominal-V t devices and metal comb capacitors, it occupies 1.3mm 2 core area, achieves 67dB SNR, 63dB peak SNDR and 67dB peak SFDR at 330MHz, and dissipates 78mW from a 1.4V supply
