Ternary inverters with BSS84 + BSS138, 10 kΩ resistors, ±2.5V supply And it works! The inverter is clearly inverting, as shown in the last plot. When input voltage is less than about -1.2V, it...

To do ternary logic, we need three values. I'm going to be using , , and as those values. You can think of as corresponding to true, as corresponding to false, and as being the extra "neither/both/whatever" value… but really they're just arbitrary symbols. A ternary function or gate is specified entirely by what to output for each possible input.

the proposed gate by combining threshold logic and ternary logic. Then, we construct basic building blocks of a ternary ALU (as logic gates, comparator, and arithmetic circuits) using the proposed gate. We show that the proposed ternary TLG improves delay, power consumption, and chip area of ternary

This project documents physical implementations of ternary logic gates and higher level sequential components. By documenting functional techniques for building up the lower level components of a ternary processor I hope to ease the way for others to begin experimenting as well.

A logic gate is a circuit that performs a basic Boolean function such as NOT, AND, OR, NAND (AND followed by NOT), NOR (OR followed by OR), XOR, and XNOR (XOR followed by NOT). Except for NOT, which has just one input, the others have two or more inputs and generate one output depending on their function.

Ternary computing is commonly implemented in terms of balanced ternary, which uses the three digits −1, 0, and +1. The negative value of any balanced ternary digit can be obtained by replacing every + with a − and vice versa. It is easy to subtract a number by inverting the + and − digits and then using normal addition.

This requires a ternary logic decoder (TLD). Logic blocks such as a ternary logic multiplexer (TLM), a TLM-based half adder and comparator can be implemented based on the TLD 17. To...

A combinational circuit consists of input variables, ternary logic gates and output variables. The output of the circuit depends only upon the present input. Logic gates accept signals from the input variables and generate output signals. This process transforms ternary information from the given input data to the required ternary output data.

In logic, a three-valued logic (also trinary logic, trivalent, ternary, or trilean, [1] sometimes abbreviated 3VL) is any of several many-valued logic systems in which there are three truth values indicating true, false and some indeterminate third value.

A ternary logic gate has an additional intermediate state; that is, it has three input logic states, "0," "1," and "2"; examples of representative ternary logic gates are LET, ROT, and LIBRA. Similarly, quaternary logic gates have four logic levels ("0," "1," "2," and "3") in the input and output states.

One approach is to base gate design on a 3-way selector. The selector (3 trit in, one trit out) can be implemented by a circuit of own design, or one standard chip like DG403 (two SPDT) or 74HC4016 (4 on/off), which are analog switches where a chip can be wired as a single 3 way.The ternary input has to be decoded (level shifting) to drive the binary switching inputs and the outputs combined.

system that requires the trits (ternary digits) to have the values +1, 0 and -1. In addition, it meets the comfortable requirement that truebe greater than false, and it permits an equivalence between logical negation and integer negation. All is not perfect, however. prefer the values 0, 1 and 2, and users of conventional Boolean logic

Ternary logic is a promising alternative to the conventional binary logic design technique, since it is possible to accomplish simplicity and energy efficiency in modern digital design due to the reduced circuit overhead such as interconnects and chip area.

The design of ternary logic gates primarily requires the multi-threshold devices. In CMOS technology, the multi-threshold devices can be implemented using the body bias effect. However, during the fabrication process, providing various bias voltages to the body terminals of metal-oxide semiconductor (MOS) transistor is a difficult task.

some of them can be mentioned here: ternary logic gates [4, 15,24,32,33], multi-digit binary-to-ternary converter [27], multiplexer-based ternary multiplier [28], quaternary full adder...

Various molecular ternary gates and circuits, including ternary NOT, ternary NOR, ternary NAND, ternary NTI, ternary PTI, ternary buffer, ternary decoder, and ternary half adder, are modeled using the method presented in [ 15] with some modifications and using the bipyridine-biborinine molecular diode model.

The ternary logic is a promising alternative to the conventional binary logic design technique. The resistive-load MOSFET-based ternary logic gates have already been proposed. The proposed memristor-based circuit replaces the large resistors by employing active load memristor in the ternary logic gates.

Ternary logic is an effective approach over the default binary logic design technique because it allows to define one more voltage level which is VDD/2 and it also allows a circuit to be...

From Figure 5, these three ternary logic gates can be realized using the uniform circuit structure (i.e., the proposed memristor-CMOS hybrid circuit). Then, the operation steps (i.e., the initialization, writing operation, and reading operation) of these three ternary logic gates are the same as that of the two-input ternary NAND gate.

Ternary system is a very promising system where more information is represented in the same number of digits compared to the binary systems. In this paper, ternary logic gates and some of their ternary circuit applications are presented using memristors and CNTFET inverter.

In logic, a three-valued logic (also trivalent, ternary, or trinary logic, sometimes abbreviated 3VL) is any of several many-valued logic systems in which there are three truth values indicating true, false and some indeterminate third value.. This is contrasted with the more commonly known bivalent logics (such as classical sentential or boolean logic) which provide only for true and false.

Implementation of basic ternary logic gates is more complex than binary gates in quantum-dot cellular automata (QCA) technology. Several models have been presented for designing ternary logic gates. ...

The quantum gates manipulate the quantum superposition and give outputs with some probability. A ternary quantum gate is a three-valued logic design, based on the superposition of 0,1, and 2. Many methods of encryption on a classical computer are based on difficulty in finding the prime factors of a large number.

Energy Efficient Tri-State CNFET Ternary Logic Gates B ACKGROUND A. Carbon Nanotube Field Effect Transistor. A carbon nanotube (CNT) is a sheet of graphene rolled up along a chirality vector [23]. The chirality vector of a CNT is defined by (n, m) pair. If n-m = 3k (k ϵ Z) then the CNT behaves like a metal, otherwise like a semiconductor [12].
