—Channel selection at the input of RF receivers can considerably relax linearity requirements, leading to low-power, compact implementations. A GSM/WCDMA/802.11b/g receiver incorporates a Miller bandpass filter and its variants to achieve a channel bandwidth from 350 kHz to 20 MHz and a noise figure of 2.9 dB while consuming 20 mW. Fabricated in 65 nm CMOS(More)
