The amplifier circuit receives an input signal and provides an output signal and includes a source degeneration inductor. The feedback circuit is coupled between a node of the amplifier circuit and the source degeneration inductor. The feedback circuit provides feedback to vary an input impedance of an amplifier including the amplifier circuit and the feedback circuit. The feedback circuit may be programmable and may be enabled to provide feedback or disabled to provide no feedback. Alternatively, the feedback circuit may always be enabled to provide feedback. In either case, the feedback circuit may have a variable gain to provide a variable input impedance for the amplifier.

摘要： A power amplifier architecture for connecting a radio frequency (RF) transceiver to an antenna. An input matching circuit is connected to its input port, and an output matching circuit is connected to its output port. An amplifier circuit includes at least one amplifier active device with a first terminal connected to the input matching segment and a second terminal connected to the output matching segment. A first harmonic feedback circuit is connected across the amplifier active device. Voltage components of emissions of one or more harmonic frequencies of a carrier fundamental frequency generated by the amplifier active device is fed back with opposite phase to the first terminal of the amplifier active device. A negative feedback is defined at a level correlated with a gain level of the amplifier active device at the harmonic frequencies of the carrier fundamental frequency. Negative feedback is minimized at the carrier fundamental frequency.

摘要： An amplifier circuit operable to provide symmetric current limiting. The amplifier circuit includes a common source amplifier for sourcing a current and receiving an voltage input, a current source, and a current limiting device coupled between the common source amplifier and the current source. The current limiting device is operable to limit the current sourced by the common source amplifier. A bias network coupled to the current limiting device biases the current limiting device. An output is coupled to the current limiting device. The amount of current that is sourced to the output of the amplifier circuit may be limited, such that current limiting is symmetrical.
