  • The use of Multiple-Valued FFT(Fast fourier Transform) is extended from binary to multiple-valued logic(MVL) circuits. A multiple-valued FFT circuit can be implemented using current-mode CMOS techniques, reducing the transitor, wires count between devices to half compared to that of a binary implementation. For adder processing in FFT, We give the number representation using such redundant digit sets are called redundant positive-digit number representation and a Redundant set uses the carry-propagation-free addition method. As the designed Multiple-valued FFT internally using PD(positive digit) adder with the digit set 0,1,2,3 has attractive features on speed, regularity of the structure and reduced complexities of active elements and interconnections. for the mutiplier processing, we give Multiple-valued LUT(Look up table)to facilitate simple mathmatical operations on the stored digits. Finally, Multiple-valued 8point FFT operation is used as an example in this paper to illuatrates how a multiple-valued FFT can be beneficial.

  • A multi-valued logic(MVL) pass gate is an important element to configure multi-valued logic. In this paper, we designed the Quaternary MIN(QMIN)/negated MIN(QNMIN) gate, the Quaternary MAX(QMAX)/negated MAX(QNMAX) gate using double pass-transistor logic(DPL) with neuron $MOS({\nu}MOS)$ threshold gate. DPL is improved the gate speed without increasing the input capacitance. It has a symmetrical arrangement and double-transmission characteristics. The threshold gates composed by ${\nu}MOS$ down literal circuit(DLC). The proposed gates get the valued to realize various multi threshold voltages. In this paper, these circuits are used 3V power supply voltage and parameter of 0.35um N-Well 2-poly 4-metal CMOS technology, and also represented HSPICE simulation results.

  • In this paper, we discuss on the design of a current mode CMOS multiplier circuit over $GF(3^m)$. Using the standard basis, we show the variation of vector representation of multiplicand by multiplying primitive element α, which completes the multiplicative process. For the $GF(3^m)$ multiplicative circuit design, we design GF(3) adder and multiplier circuit using current mode CMOS technology and get the simulation results. Using the basic gates - GF(3) adder and multiplier, we build the $GF(3^m)$ multiplier circuit and show the examples for the case m=3. We also propose the assembly of the operation blocks for a complete $GF(3^m)$ multiplier. Therefore, the proposed circuit is easily extensible to other p and m values over $GF(p^m)$ and has advantages for VLSI implementation. We verify the validity of the proposed circuit by functional simulations and the results are provided.

  • In this paper, we propose the parallel ternary logic circuit design algorithm to DCG Property with 2$^n$ nodes. To increase circuit integration, one of the promising approaches is the use of multiple-valued logic(MVL). It can be useful methods for the realization of compact integrated circuit, the improvement of high velocity signal processing using parallel signal transmission and the circuit design algorithm to optimize and satisfy the circuit property. It is all useful method to implement high density integrated circuit. In this paper, we introduce matrix equation to satisfy given DCG with 2$^n$ nodes, and propose the parallel ternary logic circuit design process to circuit design algorithm. Also, we propose code assignment algorithm to satisfy for the given DCG property. According to the simulation result of proposed circuit design algorithm, it have the following advantage ; reduction of the circuit signal lines, computation time and costs.
