Abstract :
A mixed level device and circuit analysis has been performed to study the DX-trap-induced slow transient effects on the performance degradation of AlGaAs/GaAs HEMT (high electron mobility transistor) circuits. The variation of the output pulse width and the hysteretic characteristics of the input-output voltage transfer function in DCFL (direct coupled FET logic) HEMT inverters have been simulated. It is shown that the output pulse broadening phenomena in a string of cascaded DCFL HEMT inverters are a consequence of the inverter voltage transfer function shift caused by deep traps
