A fourth order Butterworth active-RC complex filter with tuning circuits for wireless sensor networks (WSN) is presented in this paper. A method to synthesize an active-RC complex filter is proposed. A tuning system for the complex filter is designed, which is based on tuning the bit number of capacitors bank to compensate RC variations. The operational amplifier (OPA) is designed, which the gain bandwidth (GBW) is about 380MHz, the gain of the DC is 58.1dB, the phase margin is 58 and the power dissipation of the operational amplifier is about 0.6mW. The complex filter is implemented in BCD 0.18 um CMOS process. The complex filter has a bandwidth of 2 MHz, and centre frequency is 2MHz. The results of simulation show that the complex filter image rejection ratio is -48.2dB, pass-band gain is 0.379dB, the power consumption is about 4.98mW.
