  • Publication number: 20090251218
    Abstract: A variable gain amplifier for amplifying an amplifier input signal includes a current steering transconductance stage and an impedance transformation network configured to match the current steering transconductance stage to the amplifier output. The impedance transformation network includes a tapped inductor, wherein a first inductive portion of the tapped inductor is magnetically coupled with a second inductive portion of the tapped inductor. The current steering transconductance stage is configured to receive the amplifier input signal and to controllably provide a current signal to a node at the first end of the inductor or to a node electrically circuited between the amplifier output and the first end of the inductor, or to a first tap of the tapped inductor, or to a second tap of the tapped inductor.
