Optimization of phase-locked loop circuits via geometric programming
Phase-locked loop circuit geometric programming frequency phase lock loop
2015/8/11
We describe the global optimization of phase-locked loop (PLL) circuits using geometric programming (GP). Equations for the jitter, frequency range, and power of the PLL are presented in GP form. An a...
Low Cost Electronically Steered Phase Arrays for Weather Applications
dual polarization electronically scanned arrays parallel plate phased arrays polarization row-column
2014/11/7
The Electronically Steered Phased Array is one of the most versatile antennas used in radars applications. Some of the advantages of electronic steering are faster scan, no moving parts and higher rel...
Cooperative diversity with continuous phase modulation
Continuous phase modulation cooperative diversity
2011/3/22
In recent years, there has been a vast amount of research on cooperative diversity due to its potential capacity increase. Almost all of the research has been based on linear modulation formats such a...
New paths were designed for the investigations of the-tin!Imma!sh phase transitions in nanocrystalline Ge under conditions of hydrostatic stress. A second-order transition between the-tin andImmapha...
Acoustic Noise Reduction in Single Phase SRM Drives by Random Switching Technique
Single phase switched reluctance motor (SRM) harmonic spread factor (HSF) random switching technique
2010/2/2
It is known that if harmonic spectra are decreased, then
acoustic noise also decreased. Hence, this paper deals with a new
random switching strategy using DSP TMS320F2812 to decrease the
harmonics ...
Sigma-Delta Voltage to Frequency Converter With Phase Modulation Possibility
Sigma-Delta Voltage Frequency Converter Phase Modulation Possibility
2009/7/28
Voltage to frequency converter (VFC) is an oscillator whose frequency is linearly proportional to control voltage. There are two common VFC architectures: the current steering multivibrator and the ch...
Applying Closing Phase-Angle Control Technique in Bounce Reduction of AC Permanent Magnet Contactor
Phase-Angle Control Technique Bounce Reduction AC Permanent Magnet Contactor
2010/12/3
A new low-cost electronic control circuit actuator is proposed for minimizing the bouncing times of an AC permanent magnet (PM) contactor after two contacts closing. The proposed new actuator overcome...

2010/12/6
This paper describes the design and fabrication of a Ka Band PLL DRO having a fundamental oscillation frequency of 19.250 GHz, used as local oscillator in the low-noise block of a down converter...
Amplitude and Frequency Control: Stability of Limit Cycles in Phase-Shift and Twin-T Oscillators
Frequency Control Limit Cycles Phase-Shift Twin-T Oscillators
2010/12/6
We show a technique for external direct current (DC) control of the amplitudes of limit cycles both in the Phase-shift and Twin-T oscillators. We have found that amplitudes of the oscillator output vo...
