Abstract: Provided is a ramp signal generating apparatus. The ramp signal generating apparatus includes N (N is a natural number) ramp signal generating cells that are connected in series to each other. Each of the ramp signal generating cells includes a power voltage unit for supplying current source, a latch unit for latching an output voltage of the power voltage unit, and a switch unit for outputting the voltage latched by the latch unit as an output voltage in response to an input signal.

Abstract: Disclosed is a digital LDO regulator capable of performing asynchronous binary search using a binary-weighted PMOS array. The digital LDO regulator includes a PMOS array unit including a binary-weighted PMOS array and that binary searches the PMOS array asynchronously, and a mode determining unit that operates in at least one of a fine mode, a coarse mode, and a medium mode, based on an output voltage of the PMOS array unit.
