Summary:An amplifier with high power supply rejection is disclosed. In an exemplary implementation, an amplifier includes a first stage configured to receive a signal to be amplified, a second stage comprising an input transistor coupled to the first stage, and further comprising at least one additional transistor, and a voltage regulator configured to received a first supply voltage and generate a regulated supply voltage, the first supply voltage coupled to the at least one additional transistor, the regulated supply voltage coupled to the first stage and the input transistor of the second stage to improve power supply noise rejection of the apparatus.
