System and Method for Low Distortion Capacitive Signal Source Amplifier |
| 摘要 |
According to an embodiment, a method includes amplifying a signal provided by a capacitive signal source to form an amplified signal, detecting a peak voltage of the amplified signal, and adjusting a controllable impedance coupled to an output of the capacitive signal source in response to detecting the peak voltage. The controllable impedance is adjusted to a value inversely proportional to the detected peak voltage. |

1. A method comprising:
amplifying a signal provided by a capacitive signal source to form an amplified signal; detecting a peak voltage of the amplified signal; and adjusting a controllable bias voltage of the capacitive signal source in response to detecting the peak voltage, bias voltage of the capacitive signal source being adjusted to a value inversely proportional to the detected peak voltage. |
