Abstract
A new dual-polarity floating battery with accurate quiescent current control for Class AB output stages is presented. The proposed circuit has the capability to operate at very low voltages, close to the threshold voltage of a transistor. It can also operate at very high voltages with accurate quiescent current control and minimum power dissipation. Simulation results of this structure verifying the described operation are provided.
