Abstract: The disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). The disclosure relates to a technique for controlling a base station power using an artificial intelligence based technology to improve an energy efficiency of a communication network. A method performed by a base station of a communication system according to an embodiment of the disclosure may include acquiring state information, determining an active/sleep request indicator (ASRI) based on at least a part of the state information, transmitting at least one of the state information and the ASRI to a central unit, receiving, from the central unit, power control information determined based on the at least one of the state information and the ASRI, and performing a power control based on the received power control information.

Abstract: An analog-to-digital converter, including a sample/hold circuit; a reference voltage driver; a digital-to-analog converter; a comparator; and a logic circuit, wherein the reference voltage driver includes: a first voltage supplier circuit configured to output an external supply voltage provided from outside of the analog-to-digital converter; a second voltage supplier circuit configured to output a sampled reference voltage that is obtained during a sampling phase based on control signals received from the logic circuit; and a switching driver configured to electrically connect the first voltage supplier circuit to the digital-to-analog converter during a first conversion phase after the sampling phase based on the control signals received from the logic circuit, and to electrically connect the second voltage supplier circuit to the digital-to-analog converter during a second conversion phase based on the control signals received from the logic circuit.
