  • Patent number: 8008981
    Abstract: A multi-phase ultra-wideband signal generator uses differential pulse oscillators. The multi-phase ultra-wideband signal generator using differential pulse oscillators includes N pulse oscillators for generating pulse signals based on a supply of power, and further comprises N inverting amplification units for outputting inverted amplified signals of output signals of the N pulse oscillators when a number of pulse oscillators is at least two, wherein, when the number of pulse oscillators is an even or odd number, the pulse oscillators are arrayed such that they have a connection form in which output terminals OUT(+) and OUT(?) of a relevant pulse oscillator are connected to output terminals OUT(+) and OUT(?) of a next pulse oscillator through a relevant inverting amplification unit, and the connection form is consecutively applied to the pulse oscillators.
