Abstract:
An amplifier with improved noise reduction is disclosed. In an exemplary embodiment, an apparatus includes at least one capacitor configured to receive an adjustable current and generate a corresponding ramp voltage configured to control coupling between a main amplifier output and a secondary amplifier output. The apparatus also includes at least one comparator configured to adjust the adjustable current to generate the ramp voltage with selected ramp-up or ramp-down voltage characteristics.
