Abstract
An amplifier includes a bootstrap circuit for improving a linearity of the amplifier and a feed-forward circuit for modifying a voltage of the bootstrap circuit in response to a change in an input signal. Modifying the voltage using the feed-forward circuit prevents a phase-inversion condition of the amplifier.
