Patent ID: 7283595

Claim:
An ultra wide band (UWB) pulse train generator for generating an UWB pulse train in accordance with data to be transmitted, the apparatus comprising: a data input terminal for receiving n bit data to be transmitted; a trigger signal input terminal for receiving a trigger signal for triggering generation of a UWB pulse train in accordance with the n bit data; a pulse train output terminal for outputting the generated UWB pulse train; a trigger signal controller for sequentially outputting n trigger signals input through the trigger signal input terminal at regular time intervals; a latch unit for loading in parallel the n bit data input through the data input terminal and sequentially toggling the loaded n bit data by one bit whenever the trigger signal is input from the trigger signal controller; and a pulse train generator for generating polarity pulses corresponding to a direction of an edge transition in accordance with the toggling on each output signal of the latch unit and outputting the polarity pulses to the pulse train output terminal.
