Abstract
A half voltage generator includes input buffer unit that receives an input voltage and outputs control voltage and a reference voltage using a power supply voltage, and a voltage division unit that divides the power supply voltage in half and outputs the half power supply voltage in response the control voltage and reference voltage. A current mirror receives the reference voltage unit and current limits the operation of an output buffer unit, which is controlled by an output voltage of the voltage division unit to output the half power supply voltage. A push-pull driving unit is controlled by the output voltage of the output buffer unit to output the half power supply voltage, which has an improved current driving capacity, as a final output voltage.
