摘要: A CMOS transconductor for multi-mode wireless channel selection filter is presented. The linear transconductor is designed based on the flipped-voltage follower (FVF) circuit and an active resistor to achieve the transconductance tuning. The transconductance tuning can be obtained by changing the bias current of the active resistor. A third-order Butterworth low-pass filter implemented with the transconductors was designed by TSMC 0.18-mu m CMOS process. The results show that the filter can operate with the cutoff frequency of 10 MHz to 20 MHz. The tuning range would be suitable for the specifications of IEEE 802.11a/b/g/n Wireless LANs under the consideration of saving chip areas. In the design, the maximum power consumption is 13 mW with the cutoff frequency of 20 MHz under a 1.8-V supply voltage.
