  • Method and system for improving amplifier efficiency
    Publication number: 20050068104
    Abstract: One aspect of the invention is an amplifier (10), comprising an input stage amplifier (20) coupled to an output node (81). The amplifier (10) further comprises a class D output stage (50), which comprises at least two switching elements (P1, N1) and coupled to the output node (81). The amplifier (10) also comprises a control circuit (40) coupled to the output stage (50). The control circuit (40) is operable to produce a tri-state output of the output stage (50) in response to a sensed value proportional to an amount of current that flows to the output node (81).
