Analysis and characterization of GaAs Integrated digital circuits

Different GaAs logic families are analyzed and characterized in order to compare their performance. The analysis is performed adopting both depletion and enhancement devices. The study is carried out considering the inverter gate with a fan-out equal to one. The characterization is performed adopting the PSPICE simulator. The analysis shows that the performance of each devices depends on the components dimensions, too. Moreover the study confirms that the depletion devices have higher power consumption than the enhancement ones.
