摘要 A complex switched capacitor filter is formed by selecting an analog baseband prototype filter with the desired filter characteristics. This prototype is converted into a corresponding real switched capacitor filter, and finally the real switched capacitor filter is converted into a complex switched capacitor filter by replacing each element of real filter by a frequency shifted complex counterpart.
