Method and apparatus for generating in-phase (i) and quadrature-phase (q) signals

An apparatus comprising:

• an in-phase (I) input node configured to receive an I input signal;
• a first transistor having a first size, the first transistor coupled to the I input node;
• and
• a second transistor having a second size different than the first size, the second transistor coupled to the I input node,
• wherein one or more of the first transistor and the second transistor are selectively activated to calibrate the I input signal with respect to a quadrature-phase (Q) input signal to generate an I output signal and a Q output signal.

An apparatus comprising:

• means for allocating a first in-phase (I) input signal between a first I output node and a second I output node;
• means for allocating a second I input signal between the first I output node and the second I output node;
• means for allocating a first quadrature-phase (Q) input signal between a first Q output node and a second Q output node;
• and
• means for allocating a second Q input signal between the first Q output node and the second Q output node.

A computer-readable storage medium storing instructions that are executable by a processor to cause the processor to:

• generate a first in-phase (I) input signal, a second I input signal, a first quadrature-phase (Q) input signal, and a second Q input signal;
• and
• provide the first I input signal, the second I input signal, the first Q input signal, and the second Q input signal to a radio frequency (RF) interface to:
• generate a first 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;
• generate 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;
• generate a first Q 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;
• and
• generate a second Q 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.
