SYSTEM AND METHOD FOR CURRENT-MODE AMPLITUDE MODULATION
摘要
An amplifier circuit includes a power amplifier biased for saturated mode operation, and a contrallable current source to provide current to the power amplifer. The controllable current source effects desired amplitude modulation of the output signal from the power amplifier by modulating the supply current it provides responsive to an amplitude information signal.
