Abstract: The present invention relates to a technology capable of compensating for a frequency error in a quadrature relaxation oscillator. The quadrature relaxation oscillator generates a signal at a desired frequency by using a resistor and a capacitor which are less sensitive to a PVT (Process, Voltage, Temperature) variation, generates a signal at a desired frequency by compensating for an error from design, which is caused by a mismatch between circuits due to a characteristic of a semiconductor process, through a feedback lop, and removes noise.

Abstract: Disclosed is a metal source/drain-based field effect transistor having a structure that replaces a portion of a semiconductor of a source/drain with a metal and a method of manufacturing the same. By replacing the source/drain region with the source/drain metal region, increase of the parasitic resistance of a conventional three-dimensional MOSFET of several tens of nanometers, lattice mismatch of the source/drain during selective epitaxial growth, and self-heating effect can be fundamentally solved. Further, since the metal is deposited after the partial etching of the source/drain region or the selective epitaxial growth is partially performed under the conventional CMOS process, the process can be performed without using any additional mask.

Abstract: This disclosure relates to a multi-stage method and apparatus for purifying extracellular vesicles using an aqueous two-phase system, in which extracellular vesicles mixed and contaminated with proteins can be isolated and purified in a large amount at high purity within a short time through a multi-stage purification process using an aqueous two-phase system, thereby removing 95% or more of proteins and obtaining high-purity extracellular vesicles, resulting in very high processing efficiency compared to conventional techniques. In particular, the method of the disclosure does not require an expensive device or material such as an ultracentrifuge or an antibody, and can be performed at low cost and is thus economical and highly competitive. Furthermore, the extracellular vesicles thus isolated and purified can be employed in analysis methods such as RT-PCR or western blot, and can be utilized for research fields and disease diagnosis using the same.
