Patent ID: 8344796

Claim:
A switched capacitor circuit, comprising: a capacitor; an element which receives an output of the capacitor; a first switching element which is provided on an input side of the capacitor, and is turned on when a first clock signal is in a high period and is turned off when the first clock signal is in a low period; a second switching element which is provided on an output side of the capacitor, and is turned on when a second clock signal having a high period which does not overlap the high period of the first clock signal is in a high period and is turned off when the second clock signal is in a low period; and a current controlling circuit comprising a current mirror circuit and which switches a current value of a current supplied to the element by switching a current mirror ratio so as to supply a first current to the element when the first switching element is turned on, and supply a second current which is different from the first current to the element when the second switching element is turned on.
