Abstract
An N-path filter with one or more branches selectively coupled to a shared circuit node includes a first branch having a first feedback path and a second feedback path. The first feedback path includes a Miller amplifier having an input coupled to an input voltage and a first capacitor coupled to both the input voltage and an output of the Miller amplifier. The second feedback path includes a node in common with the first feedback path. The second feedback path also includes a first high pass filter coupled to the output of the Miller amplifier and a second capacitor coupled to both the first capacitor and the first high pass filter.
