This paper describes the simulations performed in order to evaluate expected performance of the voltage-controlled oscillator (VCO) based on differential ring oscillator with SCFL delay cells in 0.5μm GaAs MESFET technology. The ring oscillator structures with buffer cells are also simulated. The frequency range and tuning sensitivity are extracted. Finally, jitter simulations are performed in ...

We proposed a 2.4/5.15 GHz dual-band voltagecontrolled oscillator which consists of a voltage-controlled oscillator and an injection-locked oscillator. Its upper and lower band frequencies are 4.48 5.86 GHz and 2.24 2.93 GHz, respectively. With the power consumption of 3.2 mW, their phase noises are 115 and 121 dBc/Hz at 1 MHz offset.

• Deduced the mechanics of hearing at low sound pressure levels from measurements of basilar membrane motion. The mechanical properties of individual sections of the cochlea have been determined by examining their collective response to tones of different frequency. The conclusion is that each section acts like a harmonic oscillator with negative damping. The oscillator is controlled by negativ...

The work is based on Current Starved Voltage controlled oscillator (CSVCO) for a Phase Locked Loop (PLL) in 180 nm process. Phase locked loop’s were used in most of the application for clock generation and recovery as well. As the technology grows faster in the existing generation, there has to be quick development with the technique. In most of the application PLL’s were used for clock and dat...

The harmonic oscillator in anti de Sitter space(AdS) is discussed. We consider the harmonic oscillator potential and then time independent Schrodinger equation in AdS space. Then we apply the supersymmetric Quantum Mechanics approach to solve our differential equation. In this paper we have solved Schrodinger equation for harmonic oscillator in AdS spacetime by supersymmetry approach. The shape...

A 2.5 GHz fully integrated voltage controlled oscillator (VCO) for wireless application has been designed in a 0.35μm CMOS technology. A method for compensating the effect of temperature on the carrier oscillation frequency has been presented in this work. We compare also different VCOs topologies in order to select one with low phase noise, low supply sensitivity and large tuning frequency. Go...

A reconfigurable current mode programmable multiphase sinusoidal oscillator is realized using digitally controlled low voltage CMOS current conveyors. The realized current mode programmable multiphase sinusoidal oscillator can provide independent digital control to its oscillating frequency through n-bit control words with high resolution capability, as well as reconfigurability.
