Title:
内部電圧発生回路
Document Type and Number:
Japanese Patent JP5074542
Kind Code:
B2
Abstract:
An internal supply voltage generating circuit includes a reference voltage generator for generating a reference voltage and an internal voltage level amplifier for amplifying the reference voltage to generate an internal voltage. The internal supply voltage generator also includes a variable process compensator for adjusting the internal voltage to compensate for a variance in the internal voltage generated during amplification of the reference voltage by the internal level amplifier. The internal supply voltage further includes a driver for generating an internal supply voltage based on the internal voltage.
