According to an exemplary embodiment, an amplification module (200) includes a bias circuit (204) coupled to an input of an amplifier (202), where the bias circuit (204) is configured to charge the input of the amplifier (202) to a final bias voltage. The amplification module (200) further includes a fast charge circuit (210) configured to provide a low impedance path (246) between the bias circuit (204) and the input of the amplifier (202) when a voltage at the input of the amplifier (202) is less than the final bias voltage, thereby reducing an enable time of the amplifier (202). The fast charge circuit (210) is further configured to open the low impedance path (246) when the voltage at the input of the amplifier (202) is substantially equal to the final bias voltage. The fast charge circuit (210) includes a comparator (224) configured to cause the low impedance path (246) to open when the voltage at the input of the amplifier (202) is substantially equal to a reference voltage. |
