Abstract
A common-emitter amplifier with unilateral pre-embedding inductors includes: an input matching circuit, a first-stage amplification circuit, a first-stage interstage matching circuit, a second-stage amplification circuit, a second-stage interstage matching circuit, a third-stage amplification circuit, and an output matching circuit. The common-emitter amplifier is configured to: make an input signal sequentially enter bases of common-emitter transistors of the first-stage, second-stage, and third-stage amplification circuits, make the input signal be amplified stage by stage by the common-emitter transistors, and finally make an amplified input signal obtained by amplifying of each common-emitter transistor output through a collector of each common-emitter transistor. The common-emitter amplifier is configured to introduce interstage staggered tuning to expand bandwidth to address a narrowband problem. The unilateral pre-embedding inductors are configured to reduce a required value of the parallel embedding inductor to reduce difficulty of implementing the parallel embedding inductor, conducive to the realization of transmission lines.
