A low-voltage transconductor circuit in which the common mode gain of a first transconductor stage is compensated by a second transconductor stage (connected in parallel with the first transconductor stage) which has no differential mode transconductance, and which is connected so that its common mode transconductance offsets the common mode transconductance of the stage. This greatly reduces the common mode current signal at the output, while avoiding the necessity for a current sink at the source of the input transistors.

Abstract
A low-voltage transconductor circuit in which the common mode gain of a first transconductor stage is compensated by a second transconductor stage (connected in parallel with the first transconductor stage) which has no differential mode transconductance, and which is connected so that its common mode transconductance offsets the common mode transconductance of the stage. This greatly reduces the common mode current signal at the output, while avoiding the necessity for a current sink at the source of the input transistors.File in questo prodotto:
