Third order low pass filter embedding the bond wire transition. 7. Some results Many LNA prototypes have been implemented in a standard CMOS technology. All the LNA outputs are loaded by a 60fF capacitor in order to emulate an ADC or a pulse detector load. The measurements instruments spectrum analyser for the noise characterization and network analyser for scattering parameters measurements are isolated at LNA output by using an on chip capacitance divider. For accurate characterization of the prototypes the on chip capacitance divider has been also characterized on the same wafer to retrieve the output voltage from S parameters. The noise figure measurements are made with a spectrum analyzer and a noise source taking into account the mismatch at LNA output. The measurement results are summarized in Table 2 and compared to other published UWB LNAs.
