Abstract:
In one embodiment, a method comprising during a first calibration instance, converting at a first transconductance stage a first output voltage from a power amplifier of a transceiver to a first set of current signals; and during a second calibration instance not overlapping the first calibration instance, converting at a second transconductance stage a second output voltage from the power amplifier to a second set of current signals.
