A CMOS TH-BPAM UWB Pulse Generator
2006
This paper presents a CMOS UWB (ultra wide band) pulse generator based on binary pulse amplitude modulation with time-hopping (TH-BPAM). The basic structure of the circuit involves a time-hopping circuit and a pulse generator. The 1st derivative of the Gaussian pulse is generated by the circuit in the TH-BPAM mode, of which the width is 700ps and can be regulated. The circuit has been simulated by HSPICE with 0.18mum CMOS process and the simulation results are presented in this paper
