Claim Text:
1. A voltage generation circuit of a semiconductor apparatus, comprising: a first detection block configured to detect an output voltage and output a first detection signal; a second detection block configured to detect the output voltage and output a second detection signal; a signal generation block configured to generate a control signal in response to the first detection signal and the second detection signal; and a voltage generation block configured to generate the output voltage in response to the control signal, wherein responding speeds of the first detection block and the second detection block with respect to a variation in the output voltage are different, wherein when there is a voltage change, both the first detection block and the second detection block will activate or both will de-activate, but one of the first and second detection blocks will activate or de-activate faster than the other, and wherein the signal generation block generates the control signal which is enabled in response to the first detection signal and generates the control signal which is disabled in response to the second detection signal.
