  • Abstract
    The noise measures of both GaAs and InP transferred electron amplifiers are initially calculated analytically for the case of uniform electric field and free carrier concentration and are shown to have minimum values for nol products of about 1011 cm¿2. Noise measures for devices having realistic doping profiles are then computed by simulation and compared with the values predicted by the simple method. The best values of noise measure appear to be 7dB for GaAs and 4.5dB for InP when both diffusion and shot noise are taken into account.
