Patent ID: 8908462

Claim:
A semiconductor device, comprising; a peripheral circuit; a first power output line configured to transmit an external power voltage to the peripheral circuit; an internal voltage generation unit configured to generate an internal power voltage by using the external power voltage from the first power output line; a second power output line, different from the first output line, configured to transmit the internal power voltage to the peripheral circuit; and a first current compensator configured to provide a compensation current to a one of the first and second power output lines such that its voltage is stably maintained, the first current compensator including a first OP-amplifier having a first and second input terminals and a first output terminal, and a capacitor having first and second terminals, wherein the first input terminal is directly coupled to the other one of the first and second power output lines, the second input terminal is connected to a ground line, the first output terminal is connected to the first terminal, and the second terminal is connected to the one of the first and second power output lines.
