An integrator circuit ( 110 ) is provided including an amplifier element ( 170 ) configured to receive an input signal at an input node, amplify the input signal, and provide an amplified input signal at an output node; a feedback capacitor element ( 175 ) connected between the output node and the input node; and a current matching circuit ( 120 ) connected to the output node, and configured to sense an output voltage of the amplifier element and to provide a supplemental current (I<SUB>M</SUB>) to the input node that is less than or equal to a feedback current (I<SUB>F</SUB>) charging the feedback capacitor element. This supplemental current is substantially equal and opposite in polarity to a feedback current when the output voltage satisfies a set criterion.
