A CMOS 4.35-mW+22-dBm IIP3 Continuously Tunable Channel Select Filter for WLAN/WiMAX Receivers
A low-power high linearity CMOS G(m)-C channel select filter for WLAN/WiMAX receivers in 90-nm CMOS technology is presented. To reduce power consumption a biquad cell with simple architecture is used. A simple but efficient technique is also proposed to improve the linearity of the filter without increasing its power consumption. Coarse and fine tuning techniques are used to tune the cutoff freque
