    摘要: A linear power amplifier system using pulse area modulation includes: an envelop/phase decomposer for decomposing an input signal into an envelop signal and a phase signal; a pulse area modulator for modulating the envelop signal such that an area of the modulated envelop signal is proportional to an amplitude of the envelop signal; a control signal generator for converting the modulated envelop signal into a control signal; an automatic gain adjuster for equalizing pulse height of the modulated envelop signal; a mixer for mixing the phase signal with the output of the automatic gain adjustor to produce a RF pulse train; a power amplifier for amplifying the RF pulse train, to generate an amplified RF pulse train; and a band pass filter for restoring the original input signal from the amplified RF pulse train. The output level of the power amplifier is controlled by the control signal.

    摘要: The present invention includes a class-E power amplifier, comprising a driver stage (DS) including a first power amplifier with transistors, to which an input signal is inputted; a main stage (MS), including a second power amplifier with transistors, whose input is connected to the output of the DS; and a first LC resonator whose one end is connected to the output of the DS and the other end to the ground as an AC equivalent circuit and a second LC resonator whose one end is connected to the input of the MS and the other end to the ground as an AC equivalent circuit. In accordance with the present invention, as the voltage stress is reduced on the CMOS class-E power amplifier, the application of the high power supply voltage may be allowed and therefore the load impedance may be high while the same efficiency is maintained.
