LNA
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.
