Efficient class-G amplifier with wide output voltage swing

摘要: Various embodiments of methods and apparatus for an amplifier with wide output voltage swing are disclosed. The may include multiple stages, each associated a distinct supply voltage. Each stage contribute current to the over range voltages these ranges overlap. until reaches that stage. be as great largest minus drop equal Rdson transistor multiplied by current. In CMOS implementation, this approximately 0.15V. When is close stage, both next highest output.
