A high-order passive switched capacitor filter is proposed which can implement complex conjugate poles in its transfer function. A previously proposed structure, called time-sharing charge-traveling architecture is modified intuitively by employing a differential structure and additional clock phases. A prototype fourth order filter is designed in sampling rate of 400MHz and simulated using verified discrete-time models in Simulink. Simulation results show that the proposed structure achieves higher out of band rejection compared to the traditional charge-traveling architecture, while capacitor values are further practical for implementation.
