Claim 16:
17. An apparatus comprising:
a pipeline analog-to-digital converter comprising:
at least two stages; and
at least one amplification circuit coupled between the at least two stages, the at least one amplification circuit comprising:
amplification means for providing a gain that is based on a bias voltage and an amplification control signal; and
gain-stabilization means for substantially stabilizing the gain of the amplification means, the gain-stabilization means comprising:
replication means for providing a replica gain that is based on the bias voltage and the amplification control signal; and
means for adjusting at least one of the bias voltage or the amplification control signal based on a difference between an input voltage and an output voltage of the replication means.
