The paper proposes fourth order Butterworth complex filter for the Global Positioning System (GPS) receiver, which the center frequency of complex filter is 2MHz and bandwidth is 2 MHz. The operational amplifier (OPA) is designed as twostage fully differential OPA. The gain bandwidth (GBW) of operation amplifier reaches 300MHz, the gain of the DC is 58.3dB, the phase margin is 57 and the power of dissipation of operational amplifier is smaller than 0.56mW. The complex filter is implemented in BCD 0.18 um CMOS process. Simulation shows that the pass-band is between 1MHz and 3MHz, pass-band gain is 0.592dB, the image rejection ratio of the complex filter is more than -48dB and power consumption is about 4.485mW. The parameters of the complex filter are suitable for GPS receiver.
