The present invention relates to a QCA multiplexer using a NAND gate based on a majority vote function. In the QCA multiplexer according to the present invention, a signal obtained by inverting a first input signal and a selection signal is input, a first combinational logic cell performing a ...
Fig. 4.8. An active-HIGH 2-to-4 line decoder implemented using a 1-of-4 demultiplexer. (Note that an active-LOW device would have the AND gates replaced with NAND gates) Example 4.4 Draw the truth table of a BCD-to-decimal decoder, and show how the generation of the first four codes...
(as HFGC_n108in FIG. 1) and also the proposed glitchless multiplexer in the illustrative embodiments. In this detailed implementation of MUX108in FIG. 1, dly_clk_i302and en_i304are input signals of the same NAND gate. dly_clk_i302is passed to gm_out306only when en_i304is high. ...
NAND Gate Based QCA 2-to-1 Line Multiplexer Quantum-dot cellular automata (QCA) is important technology to be replaced with CMOS. QCA is a new paradigm for digital computing that, theoretically, is expected to reach very high operating frequencies and significant reduction of powe... JS Lee,...
Imagine if we were to approach all seven outputs of the decoder circuit in these two fashions, first developing SOP expressions using strict groupings of "1" outputs, and then using "don't care" wildcards. Which of these two approaches do you suppose would yield the simplest gate circuitry...

Thus the two low power digital circuits 4*1 multiplexer and 4-bit ripple carry adder among NAND gate, NAND gate has been designed with Multi Threshold CMOS (MTCMOS) technique. MTCMOS technique offers low leakage and high performance operation by utilizing high speed. Power consumption is ...
Application Ser. No. 191,875 entitled "A Communication Multiplexer Having A Variable Priority Scheme Using A Read Only Memory". A flop 106 sets on the next rise of clock signal PRICLK- since the D input signal HITVAL+, the output of a NAND gate 102, is at logical ONE. This forces...
1, the slave latch 52 preferably includes a NAND gate 80. The NAND gate 80 is used to gate off the SO output signal using the SE enable signal. When SE is low (functional mode), the output of the NAND gate 80 is high and remains high. In particular, the SO output will not ...
Since all the basic two-input logic functions can be implemented with MUX, it can be added to the QCA library of fundamental logic units along with the majority gate and inverter. Table 1. Implementation of basic 2-input logic functions using MUX. 2.3. Modularity Property When dealing with...
