An integrated circuit (IC) includes at least one unit cell. The at least one unit cell includes a first bit circuit configured to process a first bit signal, a second bit circuit configured to process a second bit signal, a first well spaced apart from boundaries of the at least one unit cell and biased to a first voltage, and a second well biased to a second voltage that is different from the first voltage. Each of the first and second bit circuits includes at least one transistor from among a plurality of transistors disposed in the first well.

Provided are a novel distribution automation system and its voltage control method, which can supply a stable voltage to a user by properly adjusting the settings of a control device so as to compensate for reactive power at each load terminal. The voltage control method includes: a first step of modeling a distribution system in the form of a distribution load based on constants of four terminals according to the connection type of each node and a distribution line, which constitute the distribution system; a second step of determining a formula for estimating the magnitude of a voltage at a node from a current value of an adjacent node; a third step of determining an objective function including the magnitude of the voltage, calculated through the formula determined in the second step, and a control variable for controlling the magnitude of the voltage; and a fourth step of calculating a value of the control variable to allow the determined objective function to have a minimum value and applying the calculated value to each voltage control device provided in the distribution system.
