We propose a scheme of tunable coupler based on frequency adjustable resonator for scalable quantum integrated circuits. One side the T-shape quarter-wave is short to ground through DC SQUID, which used tune coupler. In other with two open ends, either end capacitively couples different Xmon qubit, determines effective coupling between qubits. The fundamental mode dominates interaction qubits a...

This application note outlines the implementation of a single-supply, triangular wave oscillator using the MAX9000 and some passive components. The application circuit uses an op amp, comparator, and a voltage reference as active building blocks. The MAX9000 is chosen because it integrates these three components. Introduction The linearity of triangular waveforms makes triangular wave generator...

We observe a localized cnoidal (LCn) state in an electric circuit network. Its formation derives from the interplay of non-linearity and topology inherent to Su-Schrieffer-Heeger (SSH) chain inductors. Varicap diodes act as voltage-dependent capacitors, create non-linear on-site potential. For sinusoidal voltage excitation around midgap frequency, we show that response SSH follows Korteweg-de V...

A novel design approach for implementing millimeter wave wireless transceiver front-end circuits is proposed. The design methodology takes advantage in advances in Silicon Germanium (SiGe) fabrication technology and sophisticated ElectroMagnetic (EM) simulation software to ensure successful implementation of circuits designed to operate in millimeter wave range. The discussion covers basic circ...

Though millimeter wave applications have attracted much attention in recent years, they have not yet been put to practical use. The major reason for the failure may be a large transmission loss peculiar to the short wavelength. In order to overcome the inconvenience, it may be promising to introduce the technology of millimeter-wave NRD-guide circuits. In this technology, not only NRD-guide but...

The most common type of childhood-onset epilepsy syndrome is childhood absence epilepsy (CAE) with well-defined electro clinical features but unknown pathological basis. The incidence of absence epilepsy is about 2 and 8 out of every 100 000 children up to the age of 16, and the prevalence is 2 and 10% of children with any form of epilepsy. Children with CAE suffer from high rate of pretreatmen...
