ABSTRACT:
A switched capacitance circuit including: a switched capacitance section, capable of receiving as input a signal and carrying out a sampling of said signal, the section comprising at least one group of capacitors each of which has a terminal connected to a common node; at least an operational stage including at least an input terminal connected to said common node, the operational stage providing a current to said common node for charging said group of capacitors during a sampling time interval of said signal. The circuit further includes an auxiliary circuit connected to said common node and capable of being activated/deactivated by an enabling signal for injecting a further current into said common node and increasing the current provided to said common node during at least one time interval equal to a fraction of said sampling interval.
