I designed an lna,the input-referred 1dB compression point is shown below
With the increase of input power, the LNA gain increased.
I think the input-referred 1dB compression point is very strange
I feel normal as follows,
Three types of inductor models,which are ind_std,ind_sym and ind_sym_ct in Tsmc 0.18um PDK . which one is best? how to choice?
These types of capacitance which are crtmom_rf,crtmom_rf_mis,mimcap_rf and mimcap_rf_mis. how to choice?
i create a layout of LNA by TSMC 0.18um technology,i want to know the width of Metal interconnect line. the density of metal1 to metal5 1mA/um ,metal 6 1.6mA/um. LNA's DC current 5mA Tran.current 30mA How to decide to the width of the metal line.
