Design and Implementation of a Single Clock Dual-Band Switched-Capacitor Filter

This paper introduces two bands switched capacitor filters which are realized by using a single clock. The chip is LTC1068 that contains four 2 order band-pass filter. By reasonable selection of working mode and clever collocation of resistances to realize two 4 order band-pass filter which used in acoustic receiving amplifier circuit. Amplitude-frequency characteristic curves are tested in paper by frequency sweeper.
