Title:
補正電流出力回路及び補正機能付き基準電圧回路
Document Type and Number:
Japanese Patent JP6927070
Kind Code:
B2
Abstract:
A correction current output circuit comprises a first voltage dividing circuit for generating a voltage in which an output voltage from a bandgap reference voltage circuit is divided in multiple stages, first and second correction circuits connected between a power supply and a ground, and a second voltage dividing circuit for dividing the above voltage in multiple stages in a path in which a positive temperature characteristic voltage is generated with the band gap reference voltage circuit. Current output terminals of a the second transistor of the first correction circuit and a first transistor of the second correction circuit are connected to a common connection point, and a current for correcting the temperature characteristic of a reference voltage generation circuit is output from the common connection point.
