Amplifier with configurable DC-coupled or AC-coupled output

摘要: A multi-mode amplifier with configurable DC-coupled or AC-coupled output is described. In one design, the includes an and at least DC level shifting circuit. The receives amplifies input signal provides that suitable for coupling to a load in mode AC mode. circuit performs (e.g., and/or output) common-mode voltage of controlled based on whether operating operates between VDD VNEG supplies VSS may include gain stage, internal circuit, stage.
