Abstract
Aspects of the disclosure provide an amplifier. The amplifier includes a first path configured to generate a first current that has a first polarity third-order coefficient corresponding to an input signal, a swing adjustor configured to adjust a swing of the input signal, and a second path configured to generate a second current based on the swing-adjusted input signal. The second current has a second polarity third-order coefficient corresponding to the swing-adjusted input signal. The first current and the second current are combined to drive a load, such that a third-order inter-modulation (IM3) in the combined current is reduced. In addition, in a power amplifier example, parameters of the amplifier, such as a ratio of the swing adjustor, biases of transistors, a number of additional paths, are adjusted based on a detected power of the input signal, such that the IM3 reduction is achieved across a wide input power range.
