A logic simulator can prove the correctness of a digital circuit when it can be shown that only circuits implementing the system speciication will produce a particular response to a sequence of simulation commands. By simulating a circuit symbolically, veriication can avoid the combinatorial explosion that would normally occur when evaluating circuit operation over many combinations of input an...

The measured I –V data and the large-signal equivalent circuit of a resonant tunneling diode are exploited, through the analog behavioral modeling capabilities of Pspice, to create a Pspice compatible model for the diode. The model is used, with very few other components, in the simulation of a number of circuit applications including a sinusoidal wave generator, a frequency multiplier and thre...

We present a novel asynchronous RSFQ digital circuit, Test-Timed RSFQ digital circuit and system(TT), in this paper. With this asynchronous approach, data is transferred in a delay-insensitive fashion to avoid the overhead of global clock distribution and the timing uncertainty. According to the scheme, the timing signal of the logic module is generated by a test logic module. The delay module ...

In recent years, low power circuit design has been an important issue in VLSI design areas. Adiabatic logics, which dissipate less power than static CMOS logic, have been introduced as a promising new approach in low power circuit design. energy. This paper proposes an Adder circuit based on energy efficient two-phase clocked adiabatic logic. A simulative investigation on the proposed 1-bit ful...

SABYASACHI CHAKRABORTY Sr. Lecturer and Head of the Department Department of Computer Science /IT Icfai University-Sikkim. Sikkim, India. Abstract— In this paper first the traditional digital to analog conversion is discussed with circuit analysis. The concepts like propagation delay, inertial delay, step size are discussed. In the later part, the fuzzy logic circuit interface between digital t...

This paper shows how the application of a CMOS ternary logic is useful in the realisation of Delay Insensitive (01) asynchronous circuits. It is shown that fully DI asynchronous circuits are obtained with a ternary handshake protocol which employs the third logic level as idle state of the asynchronous interface. The advantages obtained are a dramatic reduction of the communication requirement ...
