Abstract: There are provided a pulse generator capable of securing a maximum transfer rate of an IR-UWB signal, while maintaining low power consumption characteristics of an all-digital scheme, and a method for generating a fine pulse. A bandwidth of a fine pulse is determined by adjusting a difference in delay time between two adjacent pulses and a pulse is generated by selecting only one of a rising edge and a falling edge of an input pulse, and thus there is no need to remove an unnecessary batch of pulses afterwards and a transfer rate is enhanced.
