Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a voltage/current converting circuit for suppressing output of DC offset current. SOLUTION: A current output means outputting difference current ioutbetween a current signal I2p amplified by a current mirror circuit 4 and a current signal I3p converted by a current mirror circuit 6 to an intermediate output terminal 7 is composed of MOSFETM9, MOSFETM10, MOSFETM11and MOSGETM12. MOSFETM9, MOSFETM10, MOSFETM11and MOSFETM12are cascode-connected to the current mirror circuits 4, 5 and 6. Thus, output of DC offset current can be suppressed. COPYRIGHT: (C)2005,JPO&NCIPI
