Abstract
Symmetric VIS SC filters simulating reference filters in classical lattice configuration can be realised with less hardware. A fifth-order PCM lowpass with only three operational amplifiers has been designed and integrated in standard CMOS Si-gate technology. VIS SC lattice filters show excellent passband-sensitivity properties. Owing to the higher stopband sensitivity with respect to element tolerances, stopband attenuation requirements in excess of about 35¿40 dB can be satisfied only by cascading lower-order SC lattice filters.
