A differential, all digital, fifth-order derivative Gaussian pulse generator is designed and fabricated in a standard 0.13μm CMOS technology for Ultra wideband (UWB) system. Usage of the differential pulse generator eliminates the need of any extra circuit for feeding differential on-chip antenna. This elimination has an enormous effect on decreasing the power consumption of transceiver. The average power consumption of proposed pulse generator is 1.63mW and 26.4μW at pulse repeating frequency (PRF) of 300MHz and 4MHz respectively with 1.2V power supply voltage. The measured output pulse amplitude is 540mV peak to peak. The proposed pulse generator fully complies with FCC regulation.
