Abstract
An integrated buffer device for a switched capacitance circuit having a buffer with an output for an output voltage dependent upon an input voltage that can be supplied by a source to the buffer device; a capacitive switching component that can be switched between a first and second condition and connected, respectively, to the source and to the buffer to transfer the input voltage onto the output; the capacitive switching component provided with a terminal having an associated stray capacitance; a charging and discharging device configured to pre-charge the stray capacitance at a reference voltage before taking up the second condition and to pre-discharge the stray capacitance before taking up the first condition.
