Abstract: A current controlled complementary metal-oxide-semiconductor transconductive amplifier arrangement includes a first transconductive amplifier and a control circuit to control the transconductance of the first transconductive amplifier. The control circuit contains a second transconductive amplifier and an error amplifier formed in a feedback circuit, a current source to provide a current flowing through a resistor so as to supply an input voltage for the second transconductive amplifier, and a second current source and the output of the second transconductive amplifier coupled to the positive input of the error amplifier such that the transconductance of the second transconductive amplifier is in a linear relation with its bias current. The bias current of the first transconductive amplifier is mirrored from the bias current of the second transconductive amplifier by a current mirror, thus the transconductance of the first transconductive amplifier is linearly current controlled.
