Abstract
An improved circuit for pseudo-N-path switched-capacitor filters (SCFs) is proposed. The circuit is faster than previously described low-noise circuits, and does not produce clock feedthrough noise in the centre of its passband. However, the number of amplifiers required is equal to the number of paths in its basic N-path cell. Computer simulation confirms the usefulness of the described circuit.
