Abstract:
An internal reference voltage generator in a semiconductor device, comprising:a temperature-compensating variable voltage generator for generating a temperature-compensated voltage; a first differential amplifier for amplifying a voltage difference between a first reference voltage connectively coupled to a first input of the first differential amplifier and a first feedback voltage connectively coupled to a second input of the first differential amplifier in order to output an internal reference voltage; a first voltage divider for generating and outputting the first feedback voltage in response to the temperature-compensated voltage, the first voltage divider further including: a first resistive element connectively coupled between an output terminal and the second input terminal of the first differential amplifier; and a second resistive element connectively coupled between the second input terminal of the first differential amplifier and a second reference voltage; and wherein the first feedback voltage is dependent on the magnitude of the temperature-compensated voltage.
