Amplifier circuit with negative feedback loop for distortion reduction |
摘要 |
<p>A circuit is designed with a first amplifier circuit (406) having a first input terminal (422), a second input terminal (404) and a first output terminal (408). The second input terminal is coupled to receive a phase-modulated signal. A second amplifier circuit (420) has a third input terminal (416), a fourth input terminal (418) and a second output terminal (422). The fourth input terminal is coupled to receive an amplitude signal. A sample circuit (410, 414) is coupled between the first output terminal and the third input terminal. <IMAGE></p> |
