Abstract
5.8 GHz is specified as the operating frequency of the electronic tolling collection (ETC) system in the new national highway network in China. A low power, robust radio frequency receiver is the key design challenge in such a system. A 3rd order butterworth low-pass filter with tunable pass-band designed for the ETC receiver was presented in this work. The design is based on a single operational amplifier in order to reduce the overall power consumption. The filter was implemented in standard CMOS 0.18 μm technology. Simulation shows that the design achieves a maximum 3-dB bandwidth of 2 MHz with 0 dB insertion loss, while the power consumption is only ~200μW.
