All practical digital circuits are usually a mixture of combinational and sequential logic. Flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. The concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...

This paper provides an Analog Behavioral Model (ABM) in PSpice of a tunnel diode The PSpice parameters are implemented as separate parameterized blocks constructed from SPICE (ABM) controlled sources and extracted through experiment. A tunnel diode based oscillator is also proposed and simulated using circuit analysis software. The behavior of the tunnel diode is simulated and compared to the m...

This paper investigates Ultra Wide Band (UWB) response of a self-actuated electromagnetic wave shield based on a diode grid both in frequency and time domain. The investigation is first carried out on a shield valid for an incident wave polarized at a specific direction only, then extended to a shield effective for an incident wave polarized at an arbitrary direction. In the frequency domain, t...

Aiming at the problems of using optocouplers to achieve logic level matching in current communication circuit, there are many components, high cost, and requirements for component parameters. Based on basic circuit matching, this paper combines The research principle triode switch, Schottky diode’s unidirectional conduction low voltage drop characteristics, introduces a inter-module with switch...

A large number of energy recovery circuits have been described to reduce the power consumption of CMOS logic circuits. Many of these circuits use diode connected transistors, accurately timed multiple clocks and self resonating power clocks. Boost logic is a 2 phase high speed energy recovery family that voltage scaling and high gate overdrive to achieve highly efficient energy recovery. In thi...

Chemically Assembled Electronic Nanotechnology is a promising alternative to CMOS fabrication. In particular, the nanoFabric has proven to be a viable solution for implementing digital circuits.

A new output structure for class E power amplifier (PA) is proposed in this paper. A series LC resonator circuit, tuned near the second harmonic of the operating frequency is added to the output circuit. This resonator causes low impedance at the second harmonic. The output circuit is designed to shape the switch voltage of the class E amplifier and lower the voltage stress of the transistor. T...
