Efficient Simulation of Solution Curves and Bifurcation Loci in Injection-Locked Oscillators

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Nonlinear Time-Domain Analysis of Injection- Locked Microwave MESFET Oscillators

In this paper, injection-locked MESFET oscillators are analyzed using several numerical models. The injectionlocking behavior of the van der Pol equation and of a more complex representation using the Curtice–Cubic MESFET model are investigated. Analysis and experimental results are compared for an NE71083 transistor oscillator operating at 0.5 GHz. The deficiencies of using a van der Pol oscil...

Phase noise characterization of subharmonic injection locked oscillators

In this work we present a detailed study of the phase noise of subharmonic injection locked oscillators (s-ILOs). A new simple and efficient model has been presented for accurately predicting the phase noise of a microwave s-ILO. The validity of the analytical technique is verified with measurement results obtained from a 5-GHz fully differential Colpitts-based s-ILO. The results showed that a ...

Superharmonic Injection Locked Oscillators as Low Power Frequency Dividers

Superharmonic injection locking is investigated in a new theoretical approach. Low power frequency dividers are designed using injection locked oscillators with cascode transistors. The Rockwell 0:5 m CMOS process is used to design a 3mW injection locked frequency divider in the 1800MHz frequency range. A 200MHz maximum locking range is achieved in simulations. 2SC3302 TOSHIBA NPN transistors a...
