In this paper, we presents 6th order elliptic continuous time Gm-C Low Pass Filter(LPF) with high linearity and tunable bandwidth characteristics. The filter is designed for a 1.8 V supply and power consumption about 3.3㎽ for Digital Video Broadcasting-Handheld(DVB-H) band (5 ㎒~8 ㎒). It can easily be tuned frequency from 4.5㎒ to 20 ㎒ and pass band gain from -20 ㏈ to 11.7 ㏈. This filter has been simulated using 0.18 ㎛ standard CMOS process design kit.
