Abstract
A data signal transmitter includes a standby voltage generator, which is configured to selectively output: (i) a data signal during an active operation mode, and (ii) first and second different standby voltages during a standby operation mode, and a repeater block. The repeater block includes: a first CMOS inverter configured to receive the first standby voltage during the standby operation mode, and a second CMOS inverter configured to receive the second standby voltage during the standby operation mode.
