Title:
内部電圧発生回路
Document Type and Number:
Japanese Patent JP4767386
Kind Code:
B2
Abstract:
An internal voltage generation circuit with a small area, which has many correction points and can provide an output voltage with a high precision, has been disclosed. In this internal voltage generation circuit, some resistors, among the resistors which are connected in series constituting the feedback circuit, have different resistance and transfer gates are provided in parallel to the resistors of different resistance. This configuration has a decode function and, therefore, the decoder can be eliminated and the number of sets of an inverter, a transfer gate, and a resistor can also be reduced, resulting in a reduction in area without a reduction in the number of the correction points.
