Abstract :
Strong dependence of finger number on minimum noise figure (NFmin) is observed in 0.18 μm MOSFETs. A lowest NFmin of 0.93 dB is measured at 5.8 GHz using 50 fingers but increases as either increasing or decreasing finger number. We have used a self-consistent S-parameter and NFmin model to analysis this abnormal finger number dependence, and the reason is due to the combined effect of reducing gate resistance and increasing substrate loss as increasing finger number.
