F. Behbahani et al., A 2.4-GHz low-IF receiver for wideband WLAN in 0.6-mu m CMOS - Architecture and front-end, IEEE J SOLI, 35(12), 2000, pp. 1908-1916
This paper presents the 2.4-GHz front-end and the first downconversion sect
ion of a fully integrated low-IF receiver. The dual-conversion receiver and
rejects the image repeatably by 60 dB using integrated polyphase filters w
ithout calibration or tuning, The gain of the RF mixer and IF amplifier is
switchable to slide the available dynamic range of the following stages bas
ed on the conditions of the input signal, The front-end and downconversion
sections drain 35 mA on average from a 3.3-V supply. Minimum cascade noise
figure is 7.2 dB, and maximum cascade IIP3 is -3.4 dBm.
