AMPLIFIER CIRCUIT |
| 摘要 |
<p>The amplifier circuit includes differential amplifier circuits (3 to 4); a peak detector circuit (7) for detecting a peak value of an output voltage of a differential amplifier circuit 4 of the last stage; an offset compensation voltage generator circuit (8) for generating an offset compensation voltage for offset compensation on the basis of a detection result of the peak detector circuit (7); and an offset output limiter circuit (9) for limiting the offset compensation voltage generated by the offset compensation voltage generator circuit (8) into a predetermined range and feeding back the limited offset compensation voltage to a differential amplifier circuit (3) of the first stage.</p> |
