Abstract :
This paper presents a reconfigurable RF circuit architecture for Multi-band Wireless Chip. The circuit can be reconstructed and tuned to various applications and the best configuration by itself. Multi-band VCO using an on-chip variable inductor achieves tuning range of 37.8%, which is one of the key circuits of reconfigurable RF circuit.
