Abstract: Certain aspects of the present disclosure generally relate to a reconfigurable active filter and techniques for using such a filter. One example reconfigurable active filter may include an amplifier including: a first input stage coupled between an input of the amplifier and an output of the amplifier, and a second input stage selectively coupled between the input of the amplifier and the output of the amplifier. The reconfigurable active filter may also include at least two feedback paths selectively coupled between the input of the amplifier and the output of the amplifier.
