... •Transformer Ratio Selection: It seems that the higher the transformer turns ratio (n), the lower the active amplifier’s gain needs to be (for the desired insertion gain), and thus the best NF. However: •Increasing “n” requires higher R1 (for proper termination of Rs) •This increases the in (input n ...
