The present specification provides a composition comprising a material of Chemical Formula 1: having a molecular weight of 500,000 to 700,000 where R1 and R2 are the same as or different from each other, and each independently is hydrogen, deuterium, or an alkyl group, and n is from 10,000 to 20,000, for forming a reverse osmosis membrane protective layer, a method for preparing a reverse osmosis membrane using the same, a reverse osmosis membrane and a water-treatment module.

Composition for forming reverse osmosis membrane protection layer, method for preparing reverse osmosis membrane using same, reverse osmosis membrane, and water treatment module

Provided are a light scattering sheet, an electronic device comprising the same, and a method of manufacturing the same.

Light-scattering sheet, electronic device comprising same, and method for producing same

Provided are a receiving module and a receiver having the same. The receiving modules includes: a comparing and detecting means for comparing a current bit of a received signal having a continuous waveform to a previous bit thereof and detecting a difference between the current bit and the previous bit; an amplifying means for amplifying the difference detected by the comparing and detecting means; and a sampling means for sampling a waveform of the received signal amplified by the amplifying means to output valid data.

Receiving module and receiver having the same

Provided is a detector for automatic gain control (AGC). The detector for AGC is used for a variable gain amplifier (VGA) including at least one VGA cell. The detector for AGC includes: first and second transistors having drains connected in common to a power supply voltage and sources connected in common to a first node, and driven in response to a non-inverting output voltage and an inverting output voltage of the VGA cell, respectively; a first current source connected between the sources of the first and second transistors and a ground voltage to supply a predetermined current; a third transistor having a drain and a source connected to the power supply voltage and a second node, respectively, and driven in response to a pre-set reference voltage; a second current source connected to the source of the third transistor and the ground voltage to supply a predetermined current; and a comparator having a non-inverting input terminal and an inverting input terminal connected to the first and second nodes, respectively, and comparing a peak voltage from the first node with a reference voltage from the second node to output a control voltage with a predetermined level to the VGA cell based on the comparison result. The detector for AGC can continuously and effectively detect an output swing of the VGA.
