A type of MOSFET fabrication technology known as complementary metal-oxide semiconductor (CMOS) employs complementary and symmetrical pairs of MOSFETs to perform logic operations. Microprocessors, microcontrollers, memory chips (including CMOS BIOS), and other digital logic circuits are all built using CMOS technology.
A form of metal-oxide-semiconductor field-effect transistor (MOSFET) fabrication technique, CMOS technology is also utilized for analog circuits such as image sensors (CMOS sensors), data converters, RF circuits (RF CMOS), and highly integrated transceivers for various sorts of communication.

MMIC stands for monolithic microwave integrated circuit, a class of integrated circuit (IC) devices that operate at microwave frequencies.
These devices often carry out tasks including high-frequency switching, low-noise amplification, power amplification, and microwave mixing. On MMIC devices, inputs and outputs are commonly matched to a 50-ohm characteristic impedance.
Since cascading MMICs no longer need an external matching network, this makes them simpler to employ. Additionally, the majority of microwave test tools are built to function in a 50-ohm environment.
Due to MMICs’ tiny size and ability to be mass-produced, high-frequency devices like mobile phones have become increasingly common.
Originally, MMICs were made from the III-V compound semiconductor gallium arsenide (GaAs). Device (transistor) speed and a semi-insulating substrate are two of its key benefits over silicon (Si), the conventional material for IC realization.
Metal-semiconductor field-effect transistors (MESFETs) were initially the active component in MMICs. High-electron-mobility (HEMT) transistors, pseudomorphic HEMTs, and heterojunction bipolar transistors have lately gained popularity.
It has been demonstrated that other III-V technologies, such as indium phosphide (InP), perform better than GaAs in terms of gain, higher cutoff frequency, and low noise. However, because of the smaller wafer sizes and more delicate materials, they also frequently cost more.
The Global CMOS MMIC market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
Infineon announced the RASIC CTRX8181 transceiver—its next radar and first product in a series of new 76- to 81-GHz radar MMICs based on 28-nm CMOS MMIC technology.
High system performance and functional robustness are provided by the transceiver’s increased signal-to-noise ratio (SNR) and linearity. The radar transceiver simultaneously provides flexibility for new software-defined vehicle architectures and a scalable platform solution for various sensors, such as corner, front, and short-range radar.
