Abstract: A water purifier is provided. A water purifier according to one aspect of the present invention may include a housing having a first accommodation space therein, and made of a paper material; a water purifier faucet disposed in the first accommodation space to receive raw water and discharge purified water; and a filter coupled to the water purifier faucet to generate the purified water by filtering the raw water, wherein the water purifier faucet includes a base frame having a second accommodation space therein in which the filter is accommodated; a water inlet module provided on one side of the base frame to supply raw water introduced from the outside to the filter; and a water outlet module provided on the other side of the base frame to receive the purified water generated by the filter and discharge it to the outside.

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.
