Method and system for sharing GM stage for a second if mixer using a polyphase clock to reduce current consumption and improve matching

摘要

A method for improving signal quality in a receiver is provided. The method may comprise generating a plurality of output signals from a single I component Gm stage and a single Q component Gm stage. The generated plurality of output signals may be mirrored from said I component Gm stage to a first I component mixer circuit and a second I component mixer circuit, and from the Q component Gm stage to a first Q component mixer circuit and a second Q component mixer circuit. An output DC signal may be generated from an output of the first I component mixer circuit and the first Q component mixer circuit. An output may be generated that may comprise a difference signal from the second I component mixer circuit and the second Q component mixer circuit.
