摘要
Low frequency (U) noise characteristics of MHBTs in the frequency range of 1Hz to 20 kHz are reported. The LF noise spectra of metamorphice heterojunction bipolar transistor (MHBT) exhibit only 1/f noise with no visible Lorentzains. The IN noise level of MHBTs is comparable to the one obtained for the referenced InP lattice-matched HBTs (LHBTs) suggesting that MHBT structures with good material quality could be achieved by the optimization of MBE material growth.
