Abstract
Systems and methods are provided for calibration of a transmitter system modulator, wherein local oscillator nodes of a mixer are held at first and second voltages, and a first offset value is determined. The terminals are then held at third and fourth voltages and a second offset value is determined. The first and second offset values are then averaged to provide a calibration offset value for the modulator.
