Abstract
A precharge voltage supplying circuit comprises a control signal generating unit for generating a first control signal in response to a power-up signal and a clock enable signal, and a precharge voltage control unit having a bleeder circuit and driving the bleeder circuit in response to the first control signal to control a precharge voltage. The precharge voltage supplying circuit can be widely used in various devices which need the generation of a voltage, a level of which is adjustable according to a PVT characteristic change, and a range of change of which is not so large.
