Abstract:
Methods, systems, and computer readable media for a tunable filter employing feedforward cancellation are disclosed. According to one aspect, the subject matter described herein includes a tunable transmissive filter that includes a splitter for splitting an input signal into a first signal and a second signal, a first modifier circuit for modifying a characteristic of the first signal to produce a modified first signal, a second modifier circuit for using feedforward cancellation to modify a characteristic of the second signal to produce a modified second signal, the second modifier circuit including an N-path filter, N being an integer greater than 0; and a combiner for combining the modified first signal and the modified second signal to produce a filtered output signal having a bandpass response.
