Description
Summary:A 3GHz source degenerated low noise amplifier (LNA), is developed to support a Radio Frequency Identifier (RFID) receiver in a variation tolerant environment. The standard LNA design was adapted for this purpose and was designed for 180nm CMOS process. The amplifier provides a forward gain (S 21 ) of 12.27dB with a Noise Figure (NF) of 1.81dB, while drawing a power of 8mW from a 1.5V supply. We also present a reliability analysis of the effect of process variations on circuit performance. Monte Carlo (MC) simulations were used to verify these effects on the NF and Stability factor (K f ) of the LNA. The resulting spread obtained shows robustness to process parameter variations.
