Adjusting phase imbalance between in-phase (I) and quadrature-phase (Q) signals

摘要

In a particular embodiment, a method of generating in-phase (I) and quadrature-phase (Q) signals includes generating a first I output signal based on a first I input signal, a second I input signal, a first Q input signal, and a second Q input signal. The method further includes generating a second I output signal based on the first I input signal, the second I input signal, the first Q input signal, and the second Q input signal. A first Q output signal is generated based on the first I input signal, the second I input signal, the first Q input signal, and the second Q input signal. A second Q output signal is generated based on the first I input signal, the second I input signal, the first Q input signal, and the second Q input signal. According to further embodiments, an apparatus is disclosed.
