Moreover, 2:1 multiplexer is also designed and explored for output transient and voltage levels. The delay of less than 2.2 ns is achieved with and a nominal deviation of 0.1 V and 0.04 V for high and low output levels respectively.
Figure 5.18. Two-input multiplexer using discrete logic gates Example 2: One-Bit Half-Adder The half-adder is an important logic design created from basic logic gates, as shown in Figure 5.19. This is a design with two inputs (A and B) and two outputs (Sum and Carry-out, Cout). Thi...

S1 =0 S0 scheme, two inputs can be selected, using two select lines, in a single LUT using two AND gates and an OR gate. The outputs of these LUTs can be combined using a wide OR gate. An N-input selector multiplexer of this structure requires at least 0.66*(N-0.5), which is ...
The main benefit of using the CMOS-based PTL circuits is that the number of transistors can be greatly reduced when compared with those based on conventional CMOS. For example, only two transistors are needed for both the OR and AND gates, whereas a total of six transistors are needed in ...
We have seen previously how logical functions, developed from the basic equations or problem definitions, can be implemented using NAND/NOR elements and techniques for reducing the number of gates demanded by a function were also described. The introduction of devices such as the multiplexer and the...
