Advanced amplifier system for ultra-wide band RF communication

A system for use in a receive chain of a communication device, the system comprising:

• an amplifying circuit configured to receive an input signal at an input of the system and to generate an oscillation based on the input signal, the input signal including an input carrier signal having a first frequency and an input modulation signal having a frequency different from the first frequency wherein the input signal has a first frequency spectrum around the first frequency;
• a sampling circuit coupled to the amplifying circuit and configured to provide a first output signal at a first output of the system, the first output signal being comprised of pulses;
• and
• one or more metamaterial (MTM) resonant circuits critically coupled in shunt with an RF path, the RF path coupling the amplifying circuit in series, the one or more MTM resonant circuits being configured to establish a frequency of operation of the system and a phase response that enhances a bandwidth of the operation to output a second output signal at a second output of the system, the second output signal comprising a substantially regenerated copy of the input signal at a higher power level than the input signal and having an output carrier signal having a second frequency and an output modulation signal having a frequency different than the second frequency, the second frequency being substantially the same as the first frequency-wherein an amplitude of the pulses is sufficiently small that the oscillation is not quenched and the second output signal appears continuous in time and wherein a second frequency spectrum of the second output signal around the first frequency is substantially identical to the first frequency spectrum;
• and
• wherein the one or more MTM resonant circuits include components having values determined to optimize an output impedance at the second output so that the second output signal is tapped out with optimal transfer of energy between the one or more MTM resonant circuits and the RF path and without disturbing properties of the system.
