REFERENCE VOLTAGE GENERATION CIRCUIT OF SEMICONDUCTOR APPARATUS

摘要

The present invention relates to the reference voltage generation circuit of a semiconductor apparatus to selectively provide reference voltage of various temperature properties according to the temperature property of a corresponding composition. The reference voltage generation circuit includes a reference voltage generation part generating reference voltages of various temperature properties; a switching part selectively outputting one among the reference voltages in response to a control signal; a temperature detection part outputting a temperature detection signal by detecting temperature change.
