RF Integrated Circuit Design

The radio frequency (RF) usually ranges from 300 kHz to 30 GHz. The RF circuit can perform RF signals which are filtered, amplified, frequency-converted, and modulated. The circuit for processing such as demodulation is an RF circuit. A radio frequency integrated circuit (RFIC) usually consists of basic functional circuits, e.g., low noise amplifiers, filters, mixers, frequency synthesizers, and power amplifiers. The RF transmitting and receiving system constitutes a carrier channel for transmitting and receiving signals of wireless systems, e.g., wireless communication, radar detection, television broadcasting, navigation, and the like. To support the ever-increasing levels of SoC integration with the low-cost requirement, the RFIC design has been moving to the advanced CMOS process nodes. Digital RF technology can transform the continuous-time analog RF functionality into digitally intensive or even all-digital implementations.
