The first path includes a first transistor that operates in a saturation region to generate a first current in response to an input signal. The first current has a first polarity third-order coefficient. The second path includes a second transistor that generates a second current in response to the input signal. The drain bias circuit is configured to bias a drain terminal of the second transistor separately from the first transistor such that the second transistor operates in a linear region to generate the second current having a second polarity third-order coefficient. The second current is combined with the first current to reduce a third-order inter-modulation in the combined current.

    摘要: 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.

    摘要: Techniques are described herein that are capable of generating a graphic flow having an unlimited number of connections between shapes. The shapes are provided in a visual representation of a workspace defined by pixels. For instance, a first shape may have an outer perimeter defined by a first subset of the pixels; a second shape may have an outer boundary defined by a second subset of the pixels, and so on. Any pixel in each subset may serve as a connection point. For example, a first pixel of the first subset may serve as a first connection point based on any of a variety of first criteria, and a second pixel of the second subset may serve as a second connection point based on any of a variety of second criteria. In accordance with this example, a connection may be provided between the first and second connection points.
