Claim:
1. A semiconductor device, comprising: a voltage generation unit that generates a first voltage having a first temperature characteristic; a constant voltage generation unit that generates a constant voltage; and an adjustment unit that generates a second voltage having a second temperature characteristic and a third voltage having a third temperature characteristic using the first voltage and the constant voltage, wherein the constant voltage generation unit generates the constant voltage independently of the adjustment unit, wherein one of the second and third temperature characteristics is an opposite characteristic to the first temperature characteristic, wherein the adjustment unit includes a first node, a second node to receive a voltage corresponding to the constant voltage, a first variable resistor disposed between the first node and the second node and a second variable resistor disposed between the second node and the voltage generation unit, and wherein the second voltage is a voltage generated at the first variable resistor and the third voltage is a voltage generated at the second variable resistor.
