AMPLIFIER WITH IMPROVED NOISE REDUCTION

摘要

An amplifier with improved noise reduction is disclosed. In an exemplary embodiment, an apparatus (300) includes at least one capacitor (326) configured to receive an adjustable current and generate a corresponding ramp voltage (Vy) configured to control coupling between a main amplifier output and a secondary amplifier output. The apparatus (300) also includes at least one comparator (M1, M2) configured to adjust the adjustable current to generate the ramp voltage (Vy) with selected ramp-up or ramp-down voltage characteristics.
