Claim:
1. A multipath feedforward band pass amplifier comprising: a plurality of amplification stages configured to form at least partially distinct amplification paths extending in parallel from an input terminal to an output terminal, each amplification path defined by a respective subset of the plurality of amplification stages and contributing to a different frequency response, wherein at least two of the amplification paths feedforwards past another amplification path at selected frequencies, at least one amplification stage is configured as a band pass resonator and at least one amplification stage is configured as a low pass amplifier; and further wherein the multipath feedforward band pass amplifier combines the different frequency responses of the amplification paths to optimize gain of the multipath feedforward band pass amplifier over a frequency range, and at least one amplification path cascades at least two amplification stages configured as band pass resonators to maximize gain at a frequency of interest within the frequency range.
