Embodiment Construction
[0019] refer to figure 1 , figure 2 . In a preferred embodiment described in the following embodiments, the low-power bidirectional noise-reducing low-noise amplifier includes: an impedance down-conversion network, a common-gate amplifying circuit and a common-source amplifying circuit with a feedback resistor; a common-gate amplifying circuit Together with a common-source amplifier circuit with feedback resistors, it forms a low-noise amplifier circuit with single-end input and double-end output; wherein, the MOS transistors are all N-type metal oxide semiconductor field effect transistors. Both the common gate input amplifier circuit and the common source amplifier circuit with feedback resistors adopt the cascode structure. The common gate input amplifier circuit is composed of MOS transistor M1 connected in series with MOS transistor M3 and its load resistor R1 connected in series between the drain of MOS transistor M3 and the power supply VDD; the common source input a...
