Abstract:
An exemplary multipath feedforward amplifier includes a plurality of amplification stages configured to form at least partially distinct amplification paths extending from an input terminal to an output terminal, each amplification path defined by a respective subset of the plurality of amplification stages, wherein at least one amplification stage is a band pass resonator. In various implementations, multipath feedforward amplifier can maximize gain at a frequency of interest by having an amplification path that cascades band pass resonators. In various implementations, the plurality of amplification paths are configured to optimize gain at a center frequency ranging from about 2 GHz to about 3 GHz.
