Abstract
An exemplary improved ground for a power amplifier circuit may include structural separation of the drive amplifier and the power amplifier grounds and cut-off of the power amplifier induced feedback current to ensure stability under a wide-range of operating conditions. The exemplary power amplifier may include a first ground coupled to a first amplifier circuit, a second ground coupled to a second amplifier circuit separate from the first ground, and the first amplifier circuit generates a drive current for the second amplifier circuit.
