In an amplifier circuit with reduced power-on transients, an amplifier has a gain to generate an output signal from an input signal and a reference signal when it is enabled, and a control circuit generates a control signal, based on the output signal and the reference signal, to be supplied to the amplifier during a power-on event. The amplifier is enabled by the control signal when the reference signal reaches the level of the output signal.
