Abstract
An amplification system can include a bias booster circuit and an amplifier that amplifies an input signal to drive a load. The bias boosting circuit can include a negative bias booster that applies a charge to an input node of the amplifier in response to a negative half-cycle of the input signal that exceeds a boost threshold level. The bias boosting circuit can also include a positive bias booster that discharges the input node of the amplifier during a positive half-cycle of the input signal that exceeds the boost threshold level. The discharging by the positive bias booster is slower than the charging by the negative bias booster to induce a bias voltage increase from a quiescent bias voltage on the input node of the amplifier.
