Abstract :
Process-related variation of noise parameters in pulse-doped GaAs MESFETs is discussed. Fluctuation in gate length of the proposed devices is shown to be a dominant source of variation in noise parameters. The statistical distribution of the minimum noise figure (Fmin) is modeled and the probability density function is described. A comparison between the calculated result of the derived equation and the measured distribution of Fmin is also shown.<>
