PURPOSE: An amplifier current drive reversal is provided to minimum voltage drop at both end of output power supply unit anytime, so minimizing power consumption of the power amplifier. CONSTITUTION: A bridge connection load(BTL) amplifier includes a first amplifier(605), a second amplifier(606), and a digital logic gate. The first amplifier and the second amplifier receive input signal(101) and amplifies it, and the first amplifier and the second amplifier include an output terminal. A pull up device control each output terminal of the first and the second amplifier to draw current from a first power rail while a pull down device controls the current to flow in the second power array. |
