ABSTRACT:
A low flicker noise operational amplifier comprises two circuit branches of the same topology and a plurality of current source pairs. For each current source pair, the two current sources are commutatively steered into the two circuit branches via two sets of differential pair in a manner controlled by a pair of complementary logical signal.
