Abstract
PURPOSE: To stably measure the input bias current of the differential amplifier, by providing the circuit saturating the active elements constituting one of the input terminals of the differential amplifier.
CONSTITUTION: In the automatic tester 10, the power supply 14 is inserted and connected in series with the conductor 6. Further, when the potential at the input terminal 2 of the differential amplifier 1 is higher than the potential of the input terminal 3, current flows only to the input terminal 2. In this case, a half the measuring current flowing to the power supply 14 is almost equal to the input bias current at the input terminal 2.
