A sixth order band-pass pseudo-two-path switched-capacitor ladder filter is designed. Sampling frequency is 300 kHz. Center frequency of the filter is 75 kHz and its bandwidth is 1.5 kHz. A fully differential telescopic OPAMP is designed for filter integrators in 0.35 μm CMOS technology using HSPICE (level 49, ver. 3.11) simulator. Pass band gain of the filter is 0.5 db with (Vin)p-p = 4V. Supply voltage is 3V. STHDR is obtained 56.1 db with (Vin)p-p = 1.2V at fin ˜ 74.9 kHz. Total power consumption of filter is 153 μW. Maximum capacitor spread is 53.
