摘要： The present invention discloses a new family of switching amplifier classes called "class E/F amplifiers." These amplifiers are generally characterized by their use of the zero-voltage-switching (ZVS) phase correction technique to eliminate of the loss normally associated with the inherent capacitance of the switching device as utilized in class-E amplifiers, together with a load network for improved voltage and current wave-shaping by presenting class-F-1 impedances at selected overtones and class-E impedances at the remaining overtones. The present invention discloses a several topologies and specific circuit implementations for achieving such performance.

摘要： A radio-frequency amplifier is provided. The radiofrequency amplifier includes a transistor having an input terminal, an output terminal, a control terminal, and a transconductance gm. A series-connected feed-through resistance Rf and feed-through capacitance Cf is connected in parallel with the input terminal and the output terminal of the transistor. A load resistance RL is connected to the output terminal. The control terminal of the transistor is biased at a fixed voltage. Part of the transistor noise follows the looped path through the feed-through resistor instead of passing on to the load, which reduces the noise figure of the amplifier. The value of gm, Rf and RL are chosen in a way to keep the input impedance of the amplifier matched to a well-defined signal source impedance.
