Original Abstract Submitted
This disclosure is directed to amplifiers including amplification circuitry, phase-shifting circuitry, and impedance matching circuitry. An amplifier may include multiple amplifier stages each amplifying an input signal by a portion of a total amplification factor of the amplifier. The amplifier may include multiple phase shifters each including a matching circuit embedded thereon. Each phase shifter may shift a phase of the input signal by a portion of a total phase shift value of the amplifier. Moreover, at least some phase shifters may provide an output signal at an output port having an output impedance matching (e.g., nearly matching) an input impedance of a subsequent circuit coupled thereto. The amplifier may include cascaded amplifier stages and phase shifters coupled to the subsequent circuit such as an antenna, a processor, and/or a memory device.
