Summary :

In this paper, a design method is described for very low sensitivity fully-balanced narrow-band band-pass switched-capacitor filters (SCF's) whose worst-case sensitivities of the amplitude responses become zero at every reflection zero. The proposed method is based on applying the low-pass to high-pass transformation, the pseudo two-path technique and the capacitance-ratio reduction technique to very low sensitivity low-pass SC ladder filters. A design example of the band-pass SCF with a quality factor Q250 is given to verify the proposed method. The remarkable advantages of this approach are very low sensitivity to element-value variations, a small capacitance spread, a small total capacitance, and clock-feedthrough noise immunity inside the passband.
