“…However, due to the lack of an efficient implementation for threshold logic gates, the developments of design automation methods for threshold logic had slowed down compared to its counterpart in Boolean logic. Recently, with the advanced development in nanotechnologies, many nano-devices have been proposed, such as resonant tunneling diode [3,37], single-electron transistor [9-11, 17, 31, 41], and quantum cellular automata [39,43], which provide promising and efficient implementations for threshold logic gates. Meanwhile, efficient CMOS implementations of threshold logic gates have also been available [7].…”

Threshold logic has been known as an alternative representation of Boolean logic due to its compactness characteristic. Recently, the developments in advanced nanotechnologies have also promised efficient implementations of threshold logic gates. Thus, many synthesis methodologies for threshold logic circuits have been proposed. Since threshold logic has a different mechanism in functional evaluation compared to the traditional Boolean logic, a threshold logic gate can represent a more complex function. As a result, the sensitization criterion in threshold logic circuits is also different. In this work, we propose a sensitization criterion for threshold logic circuits, and show its application to the static timing analysis problem. The experimental results show the accuracy of the proposed criterion.

“…The MOBILE uses two NDR devices connected in series and driven by an oscillating bias voltage to produce a mono-to-bistable transition of the circuit. The advantages of the MOBILE circuit could be not only used in the threshold logic circuit [8], but also applied to the multi-threshold threshold logic design [9].…”

The monostable-bistable transition logic element (MOBILE) is a promising application for negative differential resistance (NDR) circuit. Previously reported MOBILE is constructed by resonant tunneling diode (RTD) that is implemented by the molecular beam epitaxy (MBE) process. However in this paper, we first propose a NDR circuit composed of standard Si-based metal-oxide-semiconductor field-effect transistor (MOS) and SiGe-based heterojunction bipolar transistor (HBT). Then we demonstrate the inverter, NAND, and NOR gate operations using this MOS-HBT-NDR-based MOBILE circuit. The great advantage of this NDR-based application is that we can implement it using the standard SiGe BiCMOS process without the need for the MBE system.

“…More recently, RTD structures implementing MultiThreshold Threshold Gates (MTTGs) [6] have been proposed which further increase the functionality of the original TGs while maintaining their MOBILE operating principle and associated advantages [7], [8], [9], [10].…”

“…Data can be processed at a frequency determined by the operation speed of four chained MOBILE gates. Figure 4a depicts the circuit topology we have proposed for a generic MTTG with positive weights defined by , i.e., two inputs and two thresholds [8]. The specific function implemented by such a circuit depends on the areas of the RTDs.…”
