SAMPLE HOLD CIRCUIT, AND PIPELINE AD CONVERTER USING THE CIRCUIT |
摘要 |
<p>A switched capacitor sample hold circuit using a source-earthed input operation amplifier. This operation circuit is provided with a feed forward circuit or a feedback circuit, which is connected with a feedback capacitor of the operation amplifier through a switch. An input common voltage or the middle point voltage of an output is detected to precharge the feedback capacitor beforehand with the difference from a reference voltage thereby to suppress fluctuations in an output operation point at the time of amplifying the operation amplifier.</p> |
