A filter arrangement comprises a switching element coupled to a filter
input, wherein the switching element is controllable by a reference clock
signal. The filter arrangement further comprises an input storage
element, an output storage element, and a first and a second auxiliary
storage element. The first and the second auxiliary storage element can
each be connected in parallel to the input storage element or to the
output storage element depending on a switching signal. The output
storage element is coupled to a filter output. The filter arrangement can
be used as a loop filter in an analog-to-digital converter, wherein the
output signal of the filter arrangement is quantized to provide an output
word. Respective feedback signals can be generated from the output word
and be provided to the storage elements.
