Multi-tap direct sub-sampling mixing system for wireless receivers |
摘要 |
A multi-tap direct sub-sampling mixing system for wireless receivers is provided with a dynamically configurable passive switched capacitor filter. A front end amplifier is connected to receive a signal. The passive switched capacitor filter is connected to receive the amplified signal and has an output for providing a filtered signal. The switched capacitor filter has at least two sections that are each operable as a pole, wherein a first section of the at least two sections has sets of at least two stacked capacitors interconnected with a set of switches operable to amplify in input voltage provided to an input of the first section in response to operation of the set of switches; and a back end section connected to the output of the switched capacitor filter to receive the filtered signal.
