本文提出了一种新的低压高频脉冲产生电路，它可以完全集成在CMOS和/或BiCMOS工艺。该电路能够产生对称脉冲，这些是高斯脉冲的二阶导数，带宽高达5 GHz，并具有足够的摆动UWB应用。基于该脉冲发生器，提出了一种新型的BPSK脉冲调制器，可直接用于UWB发射机。基于0.18-/spl μ/m CMOS/BiCMOS工艺的仿真结果证实了它们的性能。
In this paper, a new low voltage high frequency pulse generation circuit is proposed which can be fully integrated in CMOS and/or BiCMOS process. The circuit is able to generate symmetrical pulses those are the second-order derivative of Gaussian pulses with a bandwidth up to 5 GHz and having sufficient swing for UWB applications. Based on the proposed pulse generator, a novel BPSK pulse modulator is also proposed and can be directly used in UWB transmitter. Simulation results based on a 0.18-/spl mu/m CMOS/BiCMOS technology confirm their performance.
