Abstract
In this paper a 6-path tunable bandpass filter which is able to reduce both Harmonic Selectivity (HS) and Harmonic Fold Back (HFB) effect simultaneously is proposed. The filter contains two channels of 6-path switched capacitor filters with same circuit structure but different clocks and is designed and simulated in GSMC 180nm CMOS technology. The simulation result shows the center frequency of the designed filter can be tuned from 20 to 560 MHz, reduction of HS at is from -34 to -40 dB, and reduction of H6 in HFB is -21 dB at the same time. The filter can be useful in SDR systems because of its good tunability, high Q and high linearity.
