Abstract
In accordance with the present invention complementary P-channel and N-channel input pairs of transistors form in an op amp. Two sets of such pairs are provided so that a transconductance range of each set of pairs is different. By combining the outputs of each of the sets of P-channel and N-channel pairs, a transconductance glitch is reduced in half.
