摘要：

A Gaussian pulse generator incorporating a pulse position modulator for use in an impulse radio ultra-wideband system is described. The pulse generator is preceded by a programonable pulse-position modulator and comprises of a cascade of complex first-order systems, which, in turn, are made up of differential pairs employing partial positive feedback. The resulting PPM Gaussian pulse generator is designed in IBM 0.18mum Bi-CMOS IC technology. Simulations predict the correct operation of the circuit for supply voltages of 1.8V and a power consumption of 30mW. The output monocycle indeed approximates a Gaussian monocycle; having a pulse duration of about 250ps. Proper modulation of the pulse in time is confirmed.
