ABSTRACT:
An integrator input circuit is disclosed. The circuit includes a voltage-current converting unit for converting a voltage into a current based on an amplifying and voltage dropping operation and outputting the thusly converted current, a current dividing unit for receiving an output current from the voltage-current converting unit and dividing the thusly received output current in a single form or multiple forms at a predetermined ratio, and an integrator for receiving the current in a single form or multiple forms and having a single input/output or a differential input/output for implementing an integrating operation, thereby implementing an integrator having a predetermined frequency bandwidth without adjusting a resistance or a capacitance by forming a current flowing path, by which the current from an output terminal of a voltage-current conversion unit converting an input voltage of an integrator into a current is divided at a predetermined ratio, and by inputting a part of the current into the integrator.
