Abstract: An integrated circuit includes: a power supply circuit configured to generate a supply voltage from at least one of first and second power source voltages; and a system load configured to operate by receiving the supply voltage through an output node of the power supply circuit, wherein the power supply circuit includes: a first low drop-output (LDO) regulator configured to generate, from the first power source voltage, a first load current flowing to the system load through the output node; and a second LDO regulator configured to selectively generate a second load current flowing to the system load through the output node, from the second power source voltage based on a difference between voltages of internal nodes of the first LDO regulator.

Abstract: Disclosed is a gamma amplifier which includes a first amplification device that receives a first input signal during a first track period in a first time period, compensates for a first offset voltage from the first input signal during a first compensation period in the first time period, and generates a first output signal during a second time period after the first time period based on a control signal, and a second amplification device that receives a second input signal during a second track period in the second time period, compensates for a second offset voltage from the second input signal during a second compensation period in the second time period, and generates a second output signal during a third time period after the second time period based on the control signal and processing circuitry configured to generate the control signal.
