The failure of the CMOS Schmitt-trigger inverter open-fault and capacitor in case a oscillator circuit cause self-oscillation device. It leads to high frequency be emitted on output side, because balance internal smaller parasitic capacitance approximately 5 – 20 pF. In this article, reduction is presented, by adding between Gate pin Drain Q1 demonstration illusion an equivalent circuit. This c...

In the process of battery system design and operation, accurate battery modelling is a key factor. Generally speaking, the electric characteristics of a given battery cell are necessary for a designer to build an equivalent circuit model. The equivalent circuit design entails the creation of both the sizing of components used in the circuit and the topology. So, it is very hard to build an accu...

An electronically tunable voltage-mode universal biquadratic filter with one input and five output terminals employing differential difference current conveyor transconductance amplifiers (DDCCTAs) has been proposed. The proposed circuit uses only two DDCCTAs, two grounded resistors and two grounded capacitors. It can realize all the five standard biquadratic filter functions, namely lowpass, b...

Shear piezoelectric motors frequently require large voltage changes on very short time scales. Since piezos behave electrically as capacitors, this requires a drive circuit capable of quickly sourcing or sinking a large amount of current at high voltages. Here we describe a novel circuit design using a high voltage amplifier, transistor switching stage, and auxiliary capacitor. This circuit can...

In this paper, we analyze a distributed amplifier based on input/output attenuation compensation. The analysis is carried out for a HEMT transistor; and a constant-k section filter is used to calculate the amplifier’s characteristics such as attenuation factor, phase constant and gain. The proposed design approach enables us to examine the tradeoff among the variables, which include the type an...

This paper presents a systematic methodology to develop statistical compact MOS models for advanced VLSI circuit simulation. Process variability in advanced CMOS technologies imposes a serious challenge for computer-aided VLSI circuit design. Therefore, statistical compact model has become indispensable for realistic assessment of the impact of random process variability on advanced VLSI circui...

The single-electron circuit in the nature of discrete dynamical systems because it changes its state discontinuously because of electron tunneling. To confirm this, we designed a sample circuit consisting of two single-electron oscillators coupled with each other through a coupling capacitor. The oscillators produce relaxation oscillation and interact with each other to generate synchronization...

Superconducting Single-Flux-Quantum (SFQ) devices have been paid much attention as alternative devices for digital circuits, because of their high switching speed and low power consumption. For large-scale circuit design, the role of computer-aided design environment is significant. As the characteristics of the SFQ devices are different from conventional devices, a new design environment is re...
