A new 3-Input XOR gate based upon the pass transistor design methodology for lowvoltage, low-voltage high-speed applications is proposed. Five existed circuits are compared with the new proposed gate. It is shown that the proposed new circuit has at least 50% improvement in power-delay product than the CPL structure and than the CMOS structure. Moreover, the proposed new circuit could also be o...
In this paper, new linearization techniques for low-voltage bipolar OTAs using hyperbolic function circuits are described. First, a design of an exponential-law circuit, which is a basic building block to compose hyperbolic sine and hyperbolic cosine circuits, is proposed. This circuit is simpler than the conventional circuit and is suitable for low-voltage application. Next, two linearized OTA...
voltage fluctuation is one of the important types of power quality aspects originated from heavy fluctuating loads. this phenomenon can influence the behavior of induction motors, produce excessive vibration and increase the ohmic losses. in this paper a simplified model to evaluate the electrical characteristics of three phase induction motors under voltage fluctuation conditions will be prese...
A new mixed-mode second order quadrature oscillator using two differential voltage current conveyors as active elements, two grounded capacitors and two grounded resistors each is proposed. The circuit provides several current and voltage outputs simultaneously. The circuit has low active and passive sensitivities. Non-ideal and parasitic study of the proposed circuit is also included. PSPICE s...
nowadays, high-voltage circuit breakers have reached such high short-circuit capabilities that testing them under the full rated voltage is generally not possible with direct tests, and they are conducted by using the synthetic test methods. although the phenomena associated with making tests is of particular importance especially in case of load break switches, but making tests are rather disr...
Electrical Arc Furnace (EAF) is large, nonlinear and time-varying load that affects power quality of the power system by producing many problems such as harmonics, flicker, current unbalance and low power factor. This paper proposes a modified Unified Power Quality Conditioner (UPQC) to reduce power quality problems of EAF and enhance its controllability. Harmonic reduction, power quality impro...
