摘要
PURPOSE: A frequency synthesizer, a method for generating an output frequency, and a method for calibrating conversion gain are provided to set conversion gain in an analog path of the frequency synthesizer to be identical to the conversion gain in a digital analog converter.;CONSTITUTION: A correction loop(300) comprises a digital inclination extracting unit(310), an analog inclination extracting unit(320), and a correction unit(330). The digital inclination extracting unit extracts digital inclination from outputs of an accumulator(130). The analog inclination extracting unit extracts analog inclination from Qout. The correction unit corrects the conversion gain of k in a digital analog converter(140) by comparing the digital inclination from the digital inclination extracting unit with the analog inclination from the analog inclination extracting unit.;COPYRIGHT KIPO 2012
