This disclosure is directed to reducing output voltage distortions of Variable Gain Amplifiers (VGAs). A VGA may include a number of amplifiers each providing a portion of a total gain of the VGA. For example, a processing circuit may select one or more of the amplifiers of the VGA to provide the output signal with a selected gain. However, the selected amplifiers may provide amplified signals with one or more distortion signals when receiving a bias voltage. Systems and methods are described to reduce or cancel the distortion signals of the selected amplifiers by providing a subthreshold nonzero bias voltage (e.g., a weak voltage) to the remaining (e.g., non-selected) amplifiers of the VGA. For example, the non-selected amplifiers may receive the weak voltage to provide distortion signals with similar voltage amplitude and out of phase compared to the distortion signals of the selected amplifiers.
