First or second generation SI cells? A comparison of sensitivity from an SI filter system viewpoint

A comparison study on SI filter sensitivity performance based on first generation and second generation cell realisation is carried out. The good sensitivity performance of second generation SI cell based structures is demonstrated by four filters and one equaliser. For SI filters based on first generation memory cells, it is shown that high ratio of clock frequency to cutoff frequency in lowpass case or high ratio of clock frequency to midband frequency in bandpass case would introduce high sensitivity performance, while the sensitivities of SI filters based on the second generation memory cell are not affected by the ratio.<>
