Spurious-mode suppression in optoelectronic oscillators
2010 IEEE International Frequency Control Symposium, 2010Optoelectronic oscillators (OEOs) are promising low phase noise radio frequency sources. However, the long fiber loops required for a high Oscillator Q also lead to spurious modes (spurs) spaced too narrowly to be filtered by standard electronic devices.

A Low-Power Multiplier With the Spurious Power Suppression Technique
IEEE Transactions on Very Large Scale Integration (VLSI) Systems, 2007This paper provides the experience of applying an advanced version of our former spurious power suppression technique (SPST) on multipliers for high-speed and low-power purposes. To filter out the useless switching power, there are two approaches, i.e., using registers and using and gates, to assert the data signals of multipliers after the data ...

A Spurious-Power Suppression Technique for Multimedia/DSP Applications
IEEE Transactions on Circuits and Systems I: Regular Papers, 2009This paper presents the design exploration and applications of a spurious-power suppression technique (SPST) which can dramatically reduce the power dissipation of combinational VLSI designs for multimedia/DSP purposes. The proposed SPST separates the target designs into two parts, i.e., the most significant part and least significant part (MSP and LSP)

Digital Suppression of Spurious PLL Tones in A/D Converters
IEEE Transactions on Signal Processing, 2011In a nonideal PLL circuit, leakage of the reference signal into the control line produces spurious tones. When the distorted PLL signal is used in an analog-to-digital converter (ADC), it injects the spurious tones into the sampled data. These distortions are particularly harmful for wideband applications, such as spectrum sensing, since they affect ...

Suppression of spurious phase shifts in an optical frequency standard
IEEE Transactions on Instrumentation and Measurement, 2001We have analyzed two types of time-domain atom-light interferometers realized by a series of beam splitting copropagating or counterpropagating laser pulses. We show how a combination of both types can be used to identify and to reduce spurious systematic phase shifts in a high-precision optical frequency standard.

Wideband band-pass filters with spurious band suppression
2010 International Conference on Wireless Communications & Signal Processing (WCSP), 2010In this paper, we investigate the cause of the second harmonic of the parasitic pass-band of coupled-serial-shunted lines band-pass filters. Filters are employed substrate suspension, wavy-edge coupling, ring resonators, and a combination of the wavy-edge coupling and ring resonators to suppress the harmonic pass-band.

Spurious radiation suppression in microstrip monopulse antenna
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2020Purpose This paper aims to introduce a new novel microstrip monopulse comparator system to reduce the spurious radiation from the comparator and the feed network for achieving better radiation performance. Design/methodology/approach Two substrate layers have been used for the microstrip monopulse comparator system.

Spurious emission and arc suppression in electron guns
2016 IEEE International Vacuum Electronics Conference (IVEC), 2016Electron guns for RF sources typically use barium dispenser cathodes to produce electron emission. Barium and oxygen diffuse to the emission surface whenever the cathode is hot to replace that lost by evaporation. The barium combines with the oxygen to form barium oxide, which reduces the surface work function.

High-Power Filters for the Suppression of Spurious Frequencies
PTGMTT International Symposium Digest, 1964The rapidly increasing number of high-power transmitters are creating a serious problem in radio frequency interference. A large part of this problem is the emission of harmonic and other spurious frequencies, which can be eliminated without affecting the signal bandwidth of the transmitter.
