Abstract: A system and method are provided to efficiently provide coverage within a large scale of a building by identifying user equipment (UE) on a floor by floor basis using a distributed antenna system (DAS) and pseudo timing advance values (TA) assigned to each floor. By applying different pseudo delays on a plurality of distributed antenna basis located at each floor, a base station can know a floor at which a user equipment is located through a timing advance value of the user equipment. When a traffic amount increases based on the measured traffic amount of each floor, the base station may increase a carrier and adjust an amplifier output on a floor by floor basis, thereby efficiently using power and maintaining a user's quality of experience (QoE).

Abstract: A digital-to-analog conversion circuit includes a first digital-to-analog converter (DAC) and a second DAC. The first DAC includes a first current generation circuit (CGC) and a first current-to-voltage converter. The first CGC generates a first current based on a first digital code received through a first terminal to provide the first current to an output node. The second DAC includes a second CGC and a second current-to-voltage converter. The second CGC generates a second current based on a second digital code received through a second input terminal to provide the second current to the output node. The first current-to-voltage converter and the second current-to-voltage converter convert a sum of the first current and the second current to a an analog voltage corresponding to a sum of the first digital code and the second digital code, and output the analog voltage at the output node.
