“…In addition, analogto-digital conversion seems to be more accurate in ternary logic systems while the ternary digital logic system can be backward compatible with the binary logic system. [47][48][49] Apparently, our PEC PD is naturally suitable for building ternary logic gates due to the bidirectional photoresponse. Using the positive and negative polarity of the photoresponses of our device, we constructed a three-value logic OR (TOR) gate with ternary inputs and ternary outputs, as schematically illustrated in Figure 6a.…”

“…It is worth noting that our ternary logic gates are based on balanced ternary logic (0, 1, -1) instead of unbalanced ternary logic (0, 1, 2), which has advantages in arithmetic operations. [48] Additionally, the operating mode of our ternary logic gate can also be changed by adjusting the light intensity, sacrificial reagents in the electrolyte, and loading metal particles. Such a device provides new insight and a strategy for the development of next-generation multi-mode optoelectronic devices in the pursuit of the high integration of optoelectronic logic circuits.…”

The elementary electronic‐logic‐gates, performing basic logic functions using electric signals as input, act as a building block of modern digital circuits. Intriguingly, the optoelectronic‐logic‐gates (OLGs), composed of optical devices, are emerging as a new logic platform which enables faster and large‐capacity data transmission and processing by using photons as input. However, the strict operation principle of classic optical devices, for example, the unidirectional photoresponse of the photodetector, restricts the functional enrichment of OLGs. Herein, reprogrammable OLGs in a photoelectrochemical (PEC)‐environment are reported by employing gallium‐nitride semiconductor p–n nanowires as photoelectrodes where bidirectional photocurrent is achieved, leading to the demonstration of various binary OLGs including “NOT”, “XOR”, and “OR”. Strikingly, thanks to the versatile tunability of PEC‐photoelectrodes, the logic function of these OLGs is switchable by simply adjusting programming inputs including light intensity, bias voltage, electrolyte condition, and the physicochemical properties of the nanowire surface. Most importantly, unique ternary OLGs, for example, ternary “OR” gates, can also be realized based on binary ones by just tuning their applied bias for higher logic complexity applications, without changing the device architecture. Such reprogrammable binary and ternary OLGs could provide a new avenue toward next‐generation logic circuits for fast computing and data‐processing in the future.

The history of ternary adders goes back to more than 6 decades ago. Since then, a multitude of ternary full adders (TFAs) have been presented in the literature. This article conducts a review of TFAs so that one can be familiar with the utilised design methodologies and their prevalence. Moreover, despite numerous TFAs, almost none of them are in their simplest form. A large number of transistors could have been eliminated by considering a partial TFA instead of a complete one. According to our investigation, only 28.6% of the previous designs are partial TFAs. Also, they could have been simplified even further by assuming a partial TFA with an output carry voltage of 0 V or V DD . This way, in a single-V DD design, voltage division inside the Carry generator part would have been eliminated and less power dissipated. As far as we have searched, there are only three partial TFAs with this favourable condition in the literature. Additionally, most of the simulation setups in the previous articles are not realistic enough. Therefore, the simulation results reported in these papers are neither comparable nor entirely valid. Therefore, the authors got motivated to conduct a survey, elaborate on this issue, and enhance some of the previous designs. Among 84 papers, 10 different TFAs (from 11 papers) are selected, simplified, and simulated in this article. Simulation results by HSPICE and 32 nm carbon nanotube FET technology reveal that the simplified partial TFAs outperform their original versions in terms of delay, power, and transistor count.

“…In the era of big data, the amount of data is growing explosively, and as a result, digital logic systems are having difficulty in processing such huge amounts of data while striving for ever-increasing efficiency [1]. To meet the demand of data processing speed and power efficiency, ternary logic has received recent attention due to its advantages of higher single-line information carrying capacity and additional logical functions [2][3][4][5][6][7]. Compared to the binary digital signal, each bit of the ternary digital signal contains more information, resulting in a higher transmission rate at the same frequency.…”

This paper proposes a unique memristor-based design scheme for a balanced ternary digital logic circuit. First, a design method of a single-variable logic function circuit is proposed. Then, by combining with a balanced ternary multiplexer, some common application-type combinational logic circuits are proposed, including a balanced ternary half adder, multiplier and numerical comparator. The above circuits are all simulated and verified in LTSpice, which demonstrate the feasibility of the proposed scheme.
