Abstract
An internal voltage generation circuit may be provided. The internal voltage generation circuit may include a pulse generation circuit configured to generate a first pulse and a second pulse in response to an external voltage. The internal voltage generation circuit may include a pulse synthesis circuit configured for synthesizing the first pulse and the second pulse to generate a synthesis pulse.

An internal voltage generation circuit comprising:
- a first pulse generation circuit configured for generating a first pulse having a pulse width which is adjusted by a first variation rate in response to an external voltage;
- a second pulse generation circuit configured for generating a second pulse having a pulse width which is adjusted by a second variation rate in response to the external voltage;
- and
- a pulse synthesis circuit configured for synthesizing the first pulse and the second pulse to generate a synthesis pulse for driving an internal voltage, wherein the pulse synthesis circuit generates the synthesis pulse having a pulse width that corresponds to a section obtained by subtracting a pulse width of the first pulse from a pulse width of the second pulse.
