Design of ultra-low voltage LNA with proper linearity in 5.2GHz for RFID tag Applications

This paper presents design of LNA by Modulated Derivative Superposition (MDS) method in 5.2GHz. Optimization & trade-offs between parasitic parameters was performed. In this design 0.18μm-TMSC technology was utilized. The design was performed with ultra-low voltage of 0.8v to reduce power consumption around 10.32mw & optimized for S11=-100.274dB, S21=-18dB & NF=0.9dB.
