This paper presents a general circuit structure based on piecewise constant approximation method for designing high-rate ultra-wideband (UWB) pulse generators. By changing the pulse duration and the number of approximation segments, both the bandwidth and the center frequency of UWB signals are tuned. The pulse generator modulates different carrier frequencies into signals with Gaussian envelop to spread the signal spectrum over the 3.1-10.6-GHz sub-bands. Also, the proposed modulator structure can be easily adopted to generate pulses with 528-MHz bandwidth within the three sub-bands in the 3.1-5-GHz range. |
