a fully differential amplifier circuit provided according to an aspect of the present invention contains a stabilization block to measure the common mode component at the output of an input stage , and to inject a current proportionate to the common mode component into each of a pair of paths forming the output of the input stage to stabilize a feedback loop formed by the input stage , an output stage and a common mode feedback block . in an embodiment , the stabilization block contains a buffer to receive the measured common mode component and to provide a buffered output . the injected current is generated based on the buffered output . due to the presence of the buffer , the differential loop may not be affected by injection of the additional current , thereby avoiding any distortions in the output signal .
