Abstract

Electronic tolling collection (ETC) system will be largely adopted in the next generation of Chinese highway network, and its operating frequency is specified to be 5.8 GHz. A limiting amplifier designed for the 5.8 GHz receiver of the ETC system is presented in this work. AC-coupled gain stage was realized to avoid additional offset cancellation mechanism. The trade-off between the small signal gain, number of stages, gain-bandwidth product, and power dissipation was studied by systematic analysis. Implemented using a standard CMOS 0.18 m process, the simulation results show that the limiting amplifier achieves overall small signal gain of 81 dB, with 20 MHz bandwidth.
