摘要:
A sigma-delta analog-to-digital converter may include a sigma-delta modulator and a decimation filter. The sigma-delta modulator may convert a first analog input signal into a first bit stream having a first pattern using sigma-delta modulation and convert a second analog input signal into a second bit stream having a second pattern using the sigma-delta modulation. The decimation filter may integrate the number of bits having a particular value in the first bit stream, output a first digital value, calculate a bitwise complement value of the first digital value, integrate the number of bits having the particular value in the second bit stream with the bitwise complement value of the first digital value as an initial value of a second digital value, and output the second digital value.

摘要:
A method includes forming a first etch target layer and a first mask layer on a substrate. Sacrificial patterns extending in a first direction are formed on the first mask layer in a second direction. Spacers are formed on sidewalls of the sacrificial patterns. After removing the sacrificial patterns, the first mask layer is etched using the spacers as an etching mask to form first masks. Second masks are formed on sidewalls of each first mask to define a third masks including each first mask and the second masks on sidewalls of each first mask. The first etch target layer is etched using the first and third masks as an etching mask to form first and second patterns in the first and second regions, respectively. Each first pattern has a first width, and each second pattern has a second width greater than the first width.

The present invention relates to an antimicrobial peptide isolated from Halocynthia aurantium, more particularly, to an antimicrobial peptide isolated from the body fluid of Halocynthia aurantium and an antimicrobial agent comprising the same as an active ingredient. The antimicrobial peptide of the present invention shows excellent antimicrobial activity under strong acidic and basic environments. Moreover, it also shows strong antimicrobial activity against resistant bacteria. So, it can be used usefully as a natural antimicrobial agent.
