A New Programmable RF System for System- On-Chip Applications
This paper presents a new programmable Radio Frequency (RF) system for a System-on-Chip (SoC) transceiver. A 5-GHz low noise amplifier (LNA) is integrated with an on-chip programmable RF circuits using 0.18?m SiGe technology. Proposed system is very useful for concurrent RF ICs in a complete RF system environment. The programmable circuit helps it to provide DC output voltages, hence, making the RF system chain automatic. The programmable RF system automatically adjusts performance of an LNA with the processor in the SoC when it goes out of the normal range of operation. It also compensates abnormal operation due to the unusual PVT (Process, Voltage and Thermal) variations in RF circuits.
