A feedback neural network for solving graph coloring problem is presented. The circuit has an associated transcendental energy function that ensures fast convergence to the exact solution. Hardware and PSPICE simulation results on random and benchmark problems have been presented. Test results are compared with existing techniques for graph coloring to show that the proposed neural network mode...

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...

In this paper, a digitally controlled single input multi-output voltage mode multifunctional biquadratic filter is presented. The circuit makes use of only a single DVCC, two grounded capacitors, one grounded and two floating resistors. The digital control is incorporated using a current-summing network (CSN). Tuning of cut-off frequency is carried out with the help of a 3–bit digital control w...

The increase of electric vehicle (EV) battery chargers connected to electric networks could lead to future harmonic problems in power systems. These loads are nonlinear devices that inject harmonic currents and pollute network voltages. Thus, battery charger modeling must be studied in detail to determine their harmonic emissions and prevent future problems. This paper investigates EV battery c...

Although the range of possible applications of the VHDL based MixED module [1] is smaller than the respective range of other mixed-signal simulators, e.g. [24], the MixED system has been shown to allow for a number of useful mixed-signal simulations, e.g. an analog inverter with operational amplifier (OA) [5], a switched capacitor circuit with OA [6], a phase-locked loop (PLL) [7] and a ∆Σ modu...

In view of changing the type of energy conversion in CMOS circuits, this paper investigates low power CMOS circuit design which adopts gradually changing power clock.

This article reviews 2 novel circuits which are floating and grounded negative inductance simulators using Current Controlled Current Differencing Amplifiers (CCCDBAs). The simulated inductance values can be controlled electronically by adjusting the bias current of the CCCDBA. Each inductance simulator comprises only 2 CCCDBAs and 1 grounded capacitor without any external resistors and any com...

A simple approximate formula for the AM-detector transfer factor, which is valid for small-signal modes as well as for large-signal ones is proposed. This formula allows one to model analytically (or numerically at the behavioural level) an AM-detector in the largesignal and small-signal modes taking into account the nonlinearity of its transfer factor. Formula validation is made by comparison ...
