Abstract
A voltage compensation circuit supplies a desired voltage to a portion to which the desired voltage is to be supplied, by compensating for voltage drops caused by line resistances of voltage supply lines. The voltage compensation circuit includes: a first voltage supply line having a first end; and a second voltage supply line having a second end. In the voltage compensation circuit, a first voltage which is higher than the desired voltage by a predetermined value is applied to the first end, and a second voltage which is lower than the desired voltage by the predetermined value is applied to the second end. The portion to which the desired voltage is to be supplied is connected to the first voltage supply line at a first junction, and the portion to which the desired voltage is to be supplied is connected to the second voltage supply line at a second junction. An amount of voltage drop in the first voltage from the first end to the first junction is substantially equal to an amount of voltage rise in the second voltage from the second end to the second junction.
