Abstract :
All RF circuit is exposed to process variations and parasitic elements, which can degrade significantly the input match and deviate its center frequency. This paper proposes a new technique to calibrate the input match and its center frequency for 2.45 GHz CMOS inductively degenerated low noise amplifier (LNA). This technique allows center frequency deviation compensation and corrects the shift of the input match quality without degrading the others characteristics of the LNA.
