Patent ID: 8154357

Claim:
A modulator for amplitude-modulating a signal defined by phase information and an envelope code, comprising: a first transistor for receiving the phase information; a second transistor for receiving the envelope code, wherein the first and second transistors each comprise first and second main electrodes, the first main electrode of one of the first and second transistors being coupled to the second main electrode of the other one of the first and second transistors and the other second main electrode constituting an output of the modulator; a further first transistor for receiving an inverse phase information of the phase information; and a further second transistor for receiving an inverse envelope code of the envelope code, wherein the further first and further second transistors each comprise first and second main electrodes, the first main electrode of one of the further first and further second transistors being coupled to the second main electrode of the other one of the further first and further second transistors and the other second main electrode being coupled to the output of the modulator.
