LNA CAPACITOR SELECTION

The LNA has an external capacitor and inductor that together form a band-pass filter. A programmable on-chip capacitor

is integrated which gives, in parallel with an external L and C, the possibility to tune the band-pass filter characteristic

during production. A parasitic capacitor has to be added to the internal capacitor value.
