Abstract
A filter is implemented as cascaded stages, and in at least one stage all resistances are implemented as double-sampled switched-capacitor circuits. In a variation, at least one resistance is implemented as a double-sampled switched-capacitor T-network. In a variation, in an integrator stage, a resistance is implemented as a transconductance, and the cutoff frequency of the integrator stage scales with a switching frequency of a DC-DC voltage converter.
