The invention relates to an amplifier device, a system, and a method. Signals are processed to facilitate the mitigation and/or cancellation of undesirable components within the signals. As consistent with one or more embodiments, input/delay circuits offset the phase of input signals presented to respective amplifiers. The phase offset is used, upon combination of the outputs of the respective amplifiers, to cancel the undesirable components of the signals. Such an approach may involve the phase offset in a digital domain, with correction upon combination of the signals as presented in an analog domain.
