Pulsed measurements and circuit modeling of weak and strong avalanche effects in GaAs MESFETs and HEMTs.

Pulsed measurements and circuit modeling of weak and strong avalanche effects in GaAs MESFETs and HEMTs.

An extensive characterization of the on-state breakdown characteristics of GaAs based MESFETs and HEMTs has been carried out by means of DC and pulsed measurements and of circuit simulations. A computer-controlled, three-terminal Transmission Line Pulse (TLP) system with 50-100 ns pulse width and su...
