摘要： A semiconductor device includes: 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. The constant voltage generation unit generates the constant voltage independently of the adjustment unit. One of the second and third temperature characteristics is an opposite characteristic to the first temperature characteristic. The device can also include a control unit that selects one of the second and third voltages in response to a predetermined setting value.

摘要： A bandgap reference circuit is provided and which includes an operating voltage, a current mirror, a first p-channel metal-oxide semiconductor (PMOS) transistor and an amplifier. The current mirror is coupled to the operating voltage. The first PMOS transistor is coupled to the operating voltage and the current mirror. The amplifier is coupled to the current mirror and the first PMOS transistor. When the bandgap reference circuit is activated, the operating voltage starts to supply voltage such that the first PMOS transistor is turned on first. When the operating voltage is higher than a preset voltage level, the first PMOS transistor is turned off, in order to complete an start-up process.
