Abstract: A group of transistors is configured to drive a bus at time slots, to express data on the bus. The group of transistors dissipates an amount of electrical energy when driving the bus to a logic level opposite to a logic level present on the bus in an immediate preceding time slot. The group of transistors is arranged to dump another amount of electrical energy. Dumping of the other amount of electrical energy is responsive to driving the bus to a logic level that is the same as present on the bus in an immediate preceding time slot. The dumped amount of electrical energy is equivalent to the amount of energy dissipated by the transistors when transitioning the bus to a different logic level. Other aspects are also described.

Abstract: An apparatus and a method correct the distortion in the output of a first amplifier (e.g., a switching amplifier) by using a second amplifier (e.g., a linear amplifier) coupled in series with the first amplifier. The output of at least the first amplifier is compared to the input signal to generate an error signal representing the distortion in the output of the first amplifier. The error signal is amplified by the second amplifier to generate a correction signal that is interposed in series with the output of the first amplifier to offset the distortion, thereby generating an output signal having little or no distortion. The apparatus and method include both feedback embodiments and feedforward embodiments.
