A dynamic reconfigurable RF circuit architecture

Abstract

This paper proposes a dynamic reconfigurable architecture for analog RF circuits. The architecture consists of RF circuits and a control circuit. The RF circuits can be reconfigured by bias voltages of transistors and variable passive components, and the RF circuit block can also be switched dynamically. The proposed architecture can realize the multi-band/mode RF circuit in single chip for the software defined radio, which achieves considerable reduction of circuit area and power consumption. On the other hand, we can obtain robust RF circuits by the dynamic reconfiguration for the process variation, the dynamic change of temperature, etc.
