SYSTEMS, METHODS, AND APPARATUSES FOR HIGH POWER COMPLEMENTARY METAL OXIDE SEMICONDUCTOR (CMOS) ANTENNA SWITCHES USING BODY SWITCHTING AND SUBSTRATE JUNCTION DIODE CONTROLLING IN MULTISTACKING STRUCTURE

摘要

A system, a method, and an apparatus for a high power complementary metal oxide semiconductor antenna switch using body switching and substrate junction diode control in a multi-stacking structure are provided to offer high power processing capability in a multi-band operation of a CMOS(Complementary Metal Oxide Semiconductor) RF(Radio Frequency) switch. A CMOS antenna switch includes an antenna, a transmission switch, and a reception switch(404). The antenna operates at a plurality of radio frequency bands. The transmission switch communicates with the antenna. The reception switch communicates with the antenna. The reception switch includes a first transistor(408) and a second transistor(410). The first transistor includes a first source(408a), a first drain(408c), and a first body substrate(408d). The second transistor includes a second source(410a), a second drain(410c), and a second body substrate(410d). The first body substrate is electrically connected to the first source or the first drain. The second body substrate is selectively connected between a resistance and a ground.
