<p>PURPOSE: A voltage type operator is provided to reduce voltage usage. CONSTITUTION: A voltage type operator comprises a first switching unit (120) and a first radiation switching unit (150). The first switching unit comprises a first variable resistor (VR_1) and a first switch (SW_1). The first variable resistor forms a resistance value determined by a digital code. When the first switch is connected to the first variable resistor, the first switch is connected to an output terminal through the first variable resistor. The first radiation switching unit comprises a first radiation variable resistor (DR_1). The first radiation variable resistor includes a resistance value and characteristics with the first variable resistor.</p>
