Abstract

The present embodiment proposes a simple and low costs circuit for a UWB pulse generator utilizing a high speed switch. The high speed switch in the present embodiment is a high gain-bandwidth product transistor. An input voltage waveform having at least one rising edge is input to the UWB pulse generator. The UWB pulse generator utilizes the rapid turn-ON characteristics of the high gain-bandwidth product transistor to generate an extremely fast falling edge waveform corresponding to the rising edge. The input voltage waveform having at least one rising edge may first be input to an initial pulse shaping portion. The fast falling edge waveform then undergoes differentiations by a first, second and third differentiator to generate a UWB pulse.
