Abstract
An integrated circuit comprises a frequency dependent circuit comprising an input node, an output node and a main bank of selectable first capacitive elements that affect a frequency characteristic of the frequency dependent circuit. The frequency dependent circuit further comprises at least one shunt bank of selectable second capacitive elements located between ground and one of the input node or the output node, wherein at least one selectable second capacitive element switched out of the frequency dependent circuit is based on a number of the selectable first capacitive elements that are switched into the frequency dependent circuit.
