Abstract:
1. A multi-phase ultra-wideband signal generator using differential pulse oscillators and an array thereof, the multi-phase ultra-wideband signal generator comprising: a plurality of pulse oscillators configured to generate pulse signals based on a supply of power and being arrayed in a connection form, each of the plurality of pulse oscillators including a plus (+) output terminal and a minus (−) output terminal; and a plurality of inverting amplification units configured to invert and amplify respective output signals of the plurality of pulse oscillators, wherein the plus (+) output terminal and the minus (−) output terminal of one of the plurality of pulse oscillators are respectively connected to the plus (+) output terminal and the minus (−) output terminal of a next one of the plurality of pulse oscillators through a respective one of the plurality of inverting amplification units, and the connection form is consecutively applied to the plurality of pulse oscillators ranging from a first one of the plurality of pulse oscillators to a last one of the plurality of pulse oscillators, and wherein, when the plurality of pulse oscillators comprises an even number of pulse oscillators, the plus (+) output terminals and the minus (−) output terminals of the last one of the plurality of pulse oscillators are respectively connected to the minus (−) output terminal and the plus (+) output terminal of the first one of the plurality of pulse oscillators through a last one of the plurality of inverting amplification units, and wherein, when the plurality of pulse oscillators comprises an odd number of pulse oscillators, the plus (+) output terminal and the minus (−) output terminals of the last one of the plurality of pulse oscillators are respectively connected to the plus (+) output terminal and the minus (−) output terminal of the first one of the plurality of pulse oscillators through the last one of the plurality of inverting amplification units.
