    Abstract: A class G headphone amplifier circuit with improved power efficiency and low EMI. It may use an automatic signal level detector to detect the signal level of incoming signals and determine positive and negative power supplies for headphone amplifiers accordingly. A voltage generator may generate pairs of differential output voltages at a plurality of amplitude steps, and supply to headphone amplifiers the pair with the amplitude determined by the automatic signal level detector. As a result, headphone amplifiers are biased according to the input signal level, and the multiple voltage rails may improve power efficiency and avoid clipping.

    Abstract: The present invention discloses a low temperature ion implantation by performing a heating process after the end of an implanting process and before the wafer is moved into the external environment. This invention actively raises wafer temperature at a time no later than implementation of the vacuum venting process, such that the condensed moisture induced by the temperature difference between a vacuum environment inside ion implanter and an external environment outside ion implanter is effectively minimized. The wafer can be heated at a loadlock, a robot for transferring wafer and/or an implantation chamber. The wafer can be heated by a gas, a liquid, a light and/or a heater embedded in a holder for holding the wafer.
