As the result of the broken-up value chain of the world, design becomes an independent commodity. Goods often are designed in one company and produced in another company. Although product is shaped in manufacturing companies of supply chain, design quality is the key sticking-point for product quality. Therefore, finished goods quality lies on the quality of Design-Manufacturing Chain. This pap...

| Crosstalk noise in long interconnections is studied based on capacitive coupling and inductive coupling. It is shown that pulse noise is induced due to inductive coupling in heterogeneous insulators. The pulse noise becomes predominant noise factor on the condition that lines become longer, line resistance become lower, the signal raising time becomes faster and dielectric constant of materia...

In this paper, an ultra-low-noise amplifier with frequency band switching capability is designed, simulated and fabricated. The two frequency ranges of this amplifier consist of the 2.4 to 2.5 GHz and 3.1 GHz to 3.15 GHz frequency bands. The designed amplifier has a noise figure of less than 1dB, a minimum gain of 23 dB and a VSWR of less than 2 in the whole frequency band. The design process s...

This paper presents a two-stage low-noise ultra-wideband amplifier to obtain high and smooth gain in 180nm CMOS Technology. The proposed structure has two common source stages with inductive feedback. First stage is designed about 3GHz frequency and second stage is designed about 8GHz. In simulation, symmetric inductors of TSMC 0.18um CMOS technology in ADS software is used.Simulations results ...

A CMOS self-mixing-free RF front-end for direct-conversion receivers is presented, which includes a differential LNA, a ring oscillator, and I/Q double-balanced harmonic mixers and buffers. It operates at 930MHz, achieves 51dB gain and 5.8dB spot noise figure at 100kHz frequency, and consumes 53mW power. A 54dB self-mixing improvement over traditional architecture is obtained. The front-end is ...

Noise figure is a commonly used system parameter that quantifies the degradation in the signal-to-noise ratio (SNR) as the signal passes through a receiving system. Because of the difficulty in defining the SNR, NF depends on how the SNR is computed and the underlying assumptions that are made. Existing NF measures and their shortcomings are explained. A new NF suitable for digital communicatio...
