“…The limitations of the proposed Gaussian generator are (1) the spectrum is not filled to the maximum extent possible with the FCC's mask, which is also the limitation of the Gaussian pulses and (2) only works for sub-GHz UWB applications but can be up-converted to higherfrequency band by frequency translation, which will inevitably increase the complexity and power consumption [73][74][75][76][77] and is not suitable for low power applications like wireless sensor networks.…”

SUMMARYGaussian pulse is widely used in communication systems. The true Gaussian function is not physically realizable, but it can be approximated through linear functions. This paper presents a Gaussian pulse approximation approach to generate a quasi-Gaussian pulse by using the transient response of a CMOS inverter. The basic structure of the proposed design includes a digital variable square pulse generator, a Gaussian pulse generator and a small antenna model. The digital variable square pulse generator makes the amplitude and width of the generated quasi-Gaussian pulse tunable. The proposed pulse generator works well for three different electrical small antenna models. The simulation results show that the generated pulse approximates the Gaussian shape very well and the radiated signal at the antennas is compliant with the Federal Communication Commission's spectral mask for the 0-960 MHz band. The simple structure of this Gaussian pulse generator lends itself to a low-power, single-chip UWB transceiver solution.
