LEVEL DETECTOR, VOLTAGE GENERATOR, AND SEMICONDUCTOR DEVICE |
摘要 |
A level detector, a voltage generator, and a semiconductor device are provided. The voltage generator includes a level detector that senses the level of an output voltage to output a sensing signal and a voltage generating unit that generates the output voltage in response to the sensing signal. The level detector may include a first reference voltage generator configured to divide a first voltage and to output a first reference voltage, a second reference voltage generator configured to divide a second voltage in response to the output voltage and to output a second reference voltage that varies as a function of temperature, and a differential amplifier configured to receive the first and second reference voltages and to output a sensing signal in response to a sensing voltage generated by amplifying a difference between the first and second reference voltages.
