Fine pulse generator and method for generating fine pulse

摘要

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.

1. A method for providing a fine pulse by an all-digital pulse generator, the method comprising:
generating a plurality of pulses delayed at predetermined time intervals; generating reverse pulses respectively corresponding to a plurality of pulses; and generating a plurality of fine pulses using the reverse pulses, wherein the generating of a plurality of reverse pulses comprises: dividing one of the plurality of pulses into first and second pulses and inputting the first and second pulses having different phases and different delay times to a logic gate; and generating a reverse pulse corresponding to the one pulse using a first delay pulse with respect to the first pulse and a second delay pulse with respect to the second pulse in the logic gate.
