| 摘要 |
A switched capacitor amplifier useful in integrated circuits and capable of low power operation, wherein the amplifier comprises at least one first hold capacitor, at least one second hold capacitor, a transconductance amplifier, first switching circuit for either (a) allowing the first hold capacitor to retain an input voltage, or (b) outputting retained input voltage through the transconductance amplifier, and a second switching circuit for either (a) feeding a voltage obtained by reversing the polarity of voltage retained by the second hold capacitor back to the transconductance amplifier for outputting as output voltage, or (b) allowing voltage retained by the first hold capacitor to be held by the second hold capacitor.
