چکیده مقاله:
In this paper, a 4th-order dual-mode active filter was implemented in 0.18μm CMOS process. Center frequency changed from 2.3 GHz to 2.7 GHz in bandselectand channel-select modes. Quality factor was 25- 100 with 17 dB Gain for band-select mode and 100-500 with 40 dB Gain in channel-select mode. Novel methodfor tuning Q was designed based on changing NIC factor. Center frequency deviations were compensated for by ananalog input. Filter power consumption and input reflection ratio were 6.45 mW and -14 dB, respectively. The main application of this filter was for IEEE 802.11 receivers.
