See full text

A receiver includes a switch network, a mixer, and an IQ mismatch (IQMM) estimation circuit. The switch network is adapted to be coupled to an output of a transmitter. The switch network is configured to selectably swap complementary signals of a differential pair. The mixer is coupled to the switch network and is configured to down-convert an output signal of the switch network. The IQ IQMM estimation circuit is coupled to the mixer, and is configured to estimate an IQMM of the transmitter based on an output signal of the mixer.
