C- CMOS C-band CMOS Bidirectional Amplifier Using Switchable Matching Network

摘要

In order to simplify the system, the present invention uses a CMOS 65-nm process to fabricate a time-division bi-directional amplifier and a conversion based on a common gate amplifier structure capable of changing the drain and source of the transistor Band CMOS bi-directional amplifier using a matching circuit, wherein a center transmission line is formed in a horizontal direction around first and second ports, and a second port is formed between the first port and the second port, A first port and an amplification stage, each of which is provided between the first port and the amplification stage and between the second port and the amplification stage, for converting the direction of the current corresponding to the amplification direction according to the directionality of the amplification stage, 2 conversion matching stage.;
