Abstract
A circuit includes first and second transconductance stages each having an input to receive a signal, and a current combiner circuit coupled to outputs of the first and second transconductance stages. The current combiner circuit forms a path from the first transconductance stage to (i) one of a plurality of output paths or (ii) multiple output paths of the output paths. The current combiner circuit severs the second transconductance stage from the output paths when the first transconductance stage forms a path to one of the output paths. The current combiner circuit forms a path from the second transconductance stage to the multiple output paths when the first transconductance stage forms a path to the multiple output paths. The current combiner circuit couples current from the first transconductance stage to (i) a first output path or a second output path or (ii) both the first and second output paths.
