Title: Base current correcting circuit
Inventor: KANOU KENJI
IPC: H03F3/343
Filed: 1982-07-21
Abstract: PURPOSE:To suppress the input bias current without degrading characteristics, by flowing a current to an NPN transistor (TR) by the collector of a lateral PNP TR in a base current correcting circuit incorporated in an operational amplifier. CONSTITUTION:Collectors 24a and 24b of a multi-collector lateral PNP TR 24 which has the emitter connected to a constant current source 22 are connected to respective bases of the first and the second NPN TRs 21 and 23. When the first and the second NPN TRs 21 and 23 have the integrated circuit structure, respective grounded emitter current amplification factors are matched well, and therefore, a current I of the constant current source 22 which is set to the same value as the collector current I of the TR21 becomes the collector current of the second NPN TR 23 approximately if each of said current amplification factor is high sufficiently. Consequently, a current is not flowed to an input terminal T1.
