摘要：

A CMOS fifth-derivative Gaussian pulse generator is presented for ultra-wideband (UWB)applications.The design exhibits low power consumption,low circuit complexity,and a precise pulse shape to inherently comply with the FCC spectrum mask for indoor UWB applications without the need for a filter. The pulse generator is implemented with a 1.8-V, 0.18- m CMOS process. The small core chip size of the pulse generator is only 217×121 m~2 because of its all digital circuit design. The measured fifth-derivative Gaussian pulse has a peak-to-peak amplitude of 158 mV and a pulse width of 800 ps. The average power dissipation is 0.6 mW with a pulse repetition frequency of 50 MHz.
