Digital systems are said to be constructed using basic logic gates. These gates are the NOR, NAND, AND, OR, EXOR & EXNOR gates. This paper presents a robust three transistors (3T) based NAND and NOR gates with precise output logic levels, yet maintaining equivalent performance than the existing logic structures. This new set of 3T logic gates are based on CMOS inverter and Pass Transistor Logic...

AbstraceIn this paper, the efficiency of a fully adiabatic logic circuit is compared with its combinational and pipelined static CMOS counterparts. The performance of each circuit is studied in terms of the maximum frequency of operation, the minimum voltage of operation, the circuit energy consumption, and the switching noise generated by the circuit. An 8-bit carry look-ahead adder is designe...

A hybrid translinear (TL) circuit constituted by two kinds of transistors, bipolar and CMOS transistors, was proposed to control its quiescent current. And a new method was introduced to analyze the hybrid TL circuit, which converted it into an uniform equivalent bipolar TL circuit. It simplified its analysis and design. This hybrid TL circuit is applied to the output stage of a class AB amplif...

A new multiplier-divider circuit using a single Current Differencing Buffered Amplifier (CDBA) and only six MOSFETs has been presented. The proposed circuit has the advantage of simultaneously realizing a multiplier and divider without changing the circuit topology. The basic functions of the proposed circuit have been verified through PSPICE simulations using a CMOS CDBA and NMOS transistors w...

The article proposes the square-rooting circuit. It bases the square-law characteristics of CMOS operating in saturation region for generating square-root function. The principle of the research is attained by the currentmirror circuit, which controls the voltages. The designed circuit dominates current as input and voltage as output.

Semiconductor manufacturing process scaling increases leakage and transistor variations, both of which are problematic for static random access memory (SRAM). Since SRAM is a critical component in modern CMOS integrated circuits, novel approaches to addressing these problems are needed. Here, six and seven transistor SRAM cells are presented that do not suffer from reduced stability when read. ...

An integrate-and-fire-type spiking feedback network is discussed in this paper. In our spiking neuron model, analog information expressing processing results is given by the relative relation of spike firing. Therefore, for spiking feedback networks, all neurons should fire (pseudo-)periodically. However, an integrate-and-fire-type neuron generates no spike unless its internal potential exceeds...

In the current paper, an improvement of piecewise curvature-corrected CMOS bandgap reference (BGR) circuit is proposed. The circuit utilizes piecewise nonlinear curvature-corrected current (PNCCC) in a conventional BGR with a current control circuit, which compensates for the voltage reference at a higher temperature range. The current control circuit (CCC) is used to reduce the total current a...
