    摘要: There is provided an integrated circuit device having an input/output electrostatic discharge (I/O ESD) protection cell. The integrated circuit device includes an I/O ESD protection cell comprising a VDD ESD protection element connected between an I/O pad and a VDD line, a ground voltage (VSS) ESD protection element connected between the I/O pad and a VSS line, and a power clamp element connected between the VDD line and the VSS line, and wherein the VDD ESD protection element, the power clamp element, and the VSS ESD protection element in the I/O ESD protection cell are adjacent to each other so they can be connected in a straight line or are arranged to partially overlap.

    摘要: A cell reselection method and mobile communication terminal using the method are disclosed. The method includes calculating first path loss parameters of a serving cell and neighboring cells; determining whether the serving cell is suitable for a communication service using the first path loss parameter thereof; performing, if the serving cell is determined to be unsuitable, a cell reselection operation; calculating, if no suitable cell is found through the cell reselection operation, a second path loss parameter of the serving cell using information on the distance from a base station of the serving cell to the mobile communication terminal; redetermining whether the serving cell is suitable using the second path loss parameter thereof; and setting an operation mode of the mobile communication terminal on the basis of the redetermination result. As a result, errors in determination of the suitability of the serving cell may be reduced.
