Unformatted text preview: Noise Figure (in dB)? Verify the minimum Noise Figure at the calculated admittance using ADS. 2) (50 pts) Now, place an ideal transformer between the 50 ohm source and the base of the common-emitter transistor, whose turns ratio provides the optimum admittance so the Noise Figure is minimized. Calculate the resulting IIP3 of the amplifier and verify your results with ADS. Plot the calculated IIP3 and NF as a function of source admittance for this amplifier. Describe the tradeoff between linearity and noise....
