Abstract

PURPOSE: To attain high-precision integration by detecting an error by integrating a zero input by an integrator and then by holding this error by capacitor while feeding it back to an operational amplifier.
CONSTITUTION: Between the inversion input and output terminal of operational amplifier 1, capacitor 2 is connected. Then, an integrator composed of this amplifier 1 and capacitor 2 integrates a zero input to detect an error by error detector 11. As a result, the detected error is held in capacitor 8 and also fed back to amplifier 1 by way of this capacitor. Consequently, the error caused by the integrator itself or drift is corrected when fed back, so that high-precision integration will be possible.
