Abstract
Provided is a switched capacitor amplifier capable of outputting a stable output voltage. The switched capacitor amplifier is capable of operating so as to eliminate a charge/discharge time difference between an input capacitor () and an output capacitor (). Accordingly, in a shift from a hold state to a sample state, for example, even if one terminal voltage (V) of the output capacitor () abruptly increases to an output voltage (VOUT), another terminal voltage (Vs) of the output capacitor () does not increase abruptly. In other words, an input voltage to an internal amplifier () does not increase abruptly. Therefore, an output voltage of the internal amplifier () becomes stable and accordingly the output voltage (VOUT) becomes stable as well.
