Abstract
An amplitude calibration element comprises a linear driver configured to receive the output of a modulator, the modulator output comprising a voltage signal having an amplitude modulated (AM) portion, a differential detector configured to receive an output of the linear driver and develop a differential signal corresponding to the AM portion, and a differential comparator configured to receive the output of the differential detector and a differential reference signal, the differential comparator configured to develop a gain control signal to control the gain of the linear driver.
