For electronic circuits, one of the most promising technology in modern days is Quantum Cellular Automata (QCA). It provides high speed, low power consumption and higher density as compared to CMOS ...

VHDL and Verilog are hardware description languages, used to describe and define logic circuits. They’re typically used to design ASICs and to program FPGAs, essentially using software to def… ...

Thus, the sequence has limited length, and the generator continuously repeats the same pattern. The generator in Figure 1 overcomes these limitations by using random noise to form the outgoing data ...

This paper presents an improved clock-phase generator, able to provide two non-overlapping phases, with an accurate phase shift of 180 degrees. The circuit relies on a modified version of the classic ...
