Abstract

A low drop-out (LDO) regulator includes a voltage-to-time converter (VTC) responsive to a reference voltage and an output voltage. The VTC generates a voltage pulse signal having: (i) a sign associated with a magnitude of the output voltage relative to a magnitude of the reference voltage, and (ii) a first pulse width proportional to a difference the output voltage and the reference voltage. A driving time-to-current converter (TIC) drives a gate node with a non-zero driving current proportional to the first pulse width of the voltage pulse signal. A slew adjusting circuit drives the gate node with a non-zero slew adjusting current, in response to the first pulse width of the voltage pulse signal being equal to or greater than reference time interval. A compensation TIC drives the output node with a non-zero compensation current having a magnitude proportional to the first pulse width of the voltage pulse signal.

Abstract

Systematic Evolution of Ligand Exponential Enrichment (SELEX) is involved to screen DNA/RNA aptamers that recognize a target molecule (including biomolecules such as nucleic acids, lipids, sugars, proteins, and peptides, hormones, low molecular weight chemical substances, toxic substances, ions, etc.). In general, in order to perform SELEX, a process of fixing a target molecule on a substrate or bead surface is required. In addition, since positive/negative monitoring is not possible in each round of a SELEX process to observe whether an aptamer library is actually well combined with a target substance, whether the SELEX process is proceeded correctly is checked by analyzing aptamers screened through several rounds. In order to remarkably solve these conventional problems and to construct a simpler and easier SELEX technique, the present disclosure provides a new SELEX technique using gold nanoparticles.

Abstract

Disclosed are a synthetic antiferromagnetic material using the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction and a multibit memory using the synthetic antiferromagnetic material that is formed. The synthetic antiferromagnetic material has a non-magnetic metal layer as an RKKY inducing layer in the center, interaction between upper and lower ferromagnetic layers is imparted according to the thickness of the RKKY inducing layer, and the magnetization of an anti-parallel state is maximized therebetween. When such synthetic antiferromagnetic materials are cumulatively stacked and tunnel barrier layers are provided therebetween, multiple bits can be stored. Namely, data may be stored by supplying a program current in parallel to the surface of the RKKY inducing layer, and a resistance state may be checked by supplying current in a vertical direction to the surface of the RKKY inducing layer.
