ABSTRACT:
An embodiment of the present invention provides a system comprising a summing device and first amplifier portion. The summing device is coupled to an output node. The first amplifier portion is coupled between an input node and the summing device. The first amplifier portion includes a first amplifier, a first filter, and first and second switches. The first amplifier is coupled between the input node and the summing device on a first path. The first filter is coupled between the input node and the first amplifier on a second path, the second path being in parallel to the first path. The first switch is coupled between the input node and the first amplifier along the first path. The second switch is coupled between the input node and the first filter along the second path.
