Design of Reconfigurable Low-passFilter for 60GHz Wireless Communication

چکیده
A third-order Chebyshevlow-pass filter, using Gm-C structure, based on Nauta’s OTA, is presented. The filter is designed for 60GHz wireless communication using 65nm CMOS process and 1.2V power supply. The cutoff frequency of the filter is required to be tuned from 1GHz to 5GHz.UsingNauta’stransconductance characteristics, the filter can be operated at ultra-high frequency band and has a high linearity and wideband frequency. From the results of the post-simulation, the cutoff frequency of the filter can be tuned from 631MHz to 5.027GHz. The gain in the pass band is nearly 2dB in high impedance. The adjacent channel rejection is about 26dB. The ripple in pass band is about1.1dB.
