Abstract
This disclosure provides systems and apparatuses for reducing flicker noise in output signals provided by a radio frequency (RF) amplifier. In some implementations, the RF amplifier may include a bias generator to provide one or more bias signals to control operating points of devices and circuits of the RF amplifier. The bias generator may include a feedback circuit to generate a current to attenuate flicker noise within the bias generator. In some implementations, the feedback circuit may receive a bias voltage and may generate the current based on a frequency of the bias voltage.
