Abstract :
A fully-differential sixth-order switched-capacitor bandpass filter is designed with a 44-MHz center frequency and a bandwidth of 6-MHz for digital video application in a standard 0.35-μm CMOS technology (Vtn = 0.6 V, Vtp = -0.8 V). With a modified double-sampling pseudo-two-path technique, the filter achieves a sampling frequency of 176 MHz and consumes 85.5 mW.
