State machine represent one type of control logic, the very important part of each integrated circuit. There can be situation when analogue designers must design this digital block but they have only a few or even no experience with this kind of design. This paper presents the design of the state machine design for analogue designers. It helps them to design a digital block - when it is simple enough...
The presented work describes behavior of contact structures of Ti/Al type on 6H-SiC N-type prepared by the sputtering technology. Optimal annealing temperature is 1065degC, minimal value of the contact resistivity is 4.89times10-4 Omegacm2. The plasma cleaned substrates produce metallizations with better adhesion and frequently with better morphology. The metallizations with 60 nm thickness of Al...
Current-voltage (I-V) characteristics of radiation detector structures based on semi-insulating (SI) GaAs obtained with new types of metallizations used to form quasi-ohmic contacts are described. Three different metals (In, Gd and Mg), having lower work function in comparison with the standard AuGeNi eutectic alloy, were used. The new contacts form a blocking barrier for holes ("minority"...
