2020 IEEE Radio Frequency Integrated Circuits Symposium (RFIC).
We propose an architecture for mobile RF transceivers which integrates RISC-V micro-controller unit (MCU) to control its internal function without requiring multiple chip-to-chip control messages from the modem. The proposed architecture is utilized
