영문 원어  : The present invention relates to an integrator using a single gain buffer. The integrator comprises: a positive differential switched-capacitor which adds a positive input signal to a value stored in a previous phase, and accumulates and stores an added value; a negative differential switched-capacitor which adds a negative input signal to a value, stored in the previous phase, and accumulates and stores an added value; a positive single gain buffer which transmits a value, obtained by adding the positive input signals, to an integration capacitor; and a negative single gain buffer which transmits a value, obtained by adding the negative input signals, to the integration capacitor. The present invention is to provide the integrator capable of having a wider bandwidth than a conventional integrator comprising a closed loop.
