Abstract
An apparatus is disclosed for gain stabilization. In an example aspect, the apparatus includes an amplifier and a gain-stabilization circuit. The amplifier has a gain that is based on a bias voltage and an amplification control signal. The gain-stabilization circuit is coupled to the amplifier and includes a replica amplifier. The replica amplifier has a replica gain that is based on the bias voltage and the amplification control signal. The gain-stabilization circuit is configured to adjust at least one of the bias voltage or the amplification control signal based on a gain error associated with the replica amplifier.
